Get Help for Cannabis Plants Problems as Quickly as Possible!

So my plant seems to be growing great. Today makes 3 weeks since I started to germinate the seed. I have topped it on the main stem and then each of the next ones thinking this should create 4 main stems at 45 degree angles to the original stem. What I am concerned about is the large fan leaves in these photos, they size and rate of the plant seems good, but these leaves are curving down evenly across the entire leaf. I ran through the page on here for plant problems and don't see examples that 100% match this. Win burn looks the closest to me, but they don't get a ton of wind.

A friend of mine looked at the photo and thought either under or over nutrient issue and mentioned to water with use some calmag which I am about to do. I haven't added much nutrients and germinated in coir / vermiculite with a biodegradable 3x4 fabric pouch. Put this straight into the container once I saw roots on the side of coming through the bottom. I thought based on the weight if anything it was a little too wet, but a new pH / moisture meter (I know they aren't great, but I tested this on mixtures I know the pH and moisture and it was right each time) says a bit on the dry side and I will water heavily tonight. Using Happy Frog Foxfarm mixed with a little of the water crystals, vermiculite and extra pearlite. Bamboo Biochar arrived the other day and worked a couple spoons into the top 2 inches (this stuff is awesome, adds such a great texture). I use bottled distilled water and temporarily spring if I need to pick up more distilled. For nutrients I used GH RapidStart @ 1/2 strength about 1/4th of waterings, Zen Products Strength (K2O3Si) 1/2 rec twice, Schultz all purpose 10-15-10 very light a couple times before transplanting and pH is around 6.5

Maybe I'm just missing the obvious, but nothing I see looks quite like this

Try watering your plant with tap water (has trace minerals for medium) and your nutes at full strength Ph'ed to 6.5 in and out. Water/feed to drip out of the bottom not sides. Let it dry to damp only before watering again. Pictures are better if not in grow light. Highly recommend a PH pen, the "investment" is worth your "time" !
Good Luck ! Good Growing !!

[MmmHmmml3]

Thanks, I also moved the lights up a bit. I did have them a little closer than recommended and added another 2x50w blurple cob. My camera isn't that great, but I have a funny feeling it might be lights and using the heater which blew warm air over them for a while. I think they were too wet and dry at the same time if that makes sense.

I did what you mentioned and will see how they look. I don't think I was watering enough at first and the top 2 inches keeps drying out in less than a day. Now since heavy watering the top is still moist. Also lowered temps down to 72 - 75.

I angled it so all 3 cobs are directly over this small area with the 3 small plants. Need a lux meter to see if it's too much.

Give them some time to recover after your changes and remember not to over think things.

Anybody with this symptoms ? Light Dep - 2 week of flowering ; Medium - potting mix 707 reused (peat moss,coco based ) ; GH nutritions ; 5 gallon plastic pots ; Run to waste;
Symptoms : Droppy leaves , twisted new growth , looks like overwater ,slow growth . Just to mention that all the Greenhouse is affected the other GH is doing fine .


1. Overwater , it may be/but nothing crazy i have never water with wet top soil , so not too bad,but yeah maybe slightly overwater, which is easy to cure if u let them dry for few days, it didnt reolve the problem
2. Root Bound - i ripped the grow bag as u can see on the pic there is no horizontal or vertical grow at all !
3.Root issues - roots look fine on the pic
4. Mites - def there is which is normal for outdoor grow, i spray 3 times per week , i have seen really bad infestation with no problem for the plant, there is no webbing .
5. Wind burn - it is windy , but nothing crazy to affect all the plants

[Colombo]

Hello B, Do your bags have holes around them for air circulation and drainage ? Temp in green house? Humidity? The bag cut open looks very dry. Spraying in a green house the leaves get stressed from humidity and warm soil can cause your drooping also. Good Growing !!

[Radja]

Hello everyone,

I would like to ask your help with my ladies
2 autoflowers (sticky beast from zamnesia).
2x 450 led viparspectra.
Lightmix from plagron 11liter pot.
1 month old and started feeding 1/4 of the recommended dose so 1.25ml in 1liter and ph 6-6.5, on week 3.
I thought they started burning after the first time, so I gave them plain water the next 2 times of watering, ph 6 because soil was ph7 and more to flush a little. Now it looks like they had too much water and the problem only keeps getting worse.
One is not growing as fast as the other one.
It's also the same problem I had last time, only with different strains. This strains didn't suffer anything from my mistakes then.. (to much nutrients and not watering till runoff) didn't make the same mistake again.
Maybe root problems? potassium deficiency?
I really don't know anymore .
Thanks in advance!

[SoOrbudgal]

Radja I think you figured it out with the over water and nutes. You flushed now perhaps a drying period. Lots of good info on this site and helpful more experienced growers than me that can perhaps share their ideas. Autos are more sensitive than reg. plants and that strain could be telling you that by how it reacts.

[Radja]

Thanks for your reply. I'm digging true the site over and over again, but I can't seem to figure it out because the problem keeps spreading on the fan leaves even after flushing . So maybe not enough nutes, but that doesn't make sense since the problem started after feeding
wonderful but complex Ladies

[alltatup]

Hi Radja, The plants look pretty good in your pictures, but if the problem is continuing, could you please post some new pictures?

Looking at the first picture, it occurs to me that maybe your roots are root-bound; the big girl might need a bigger pot.

I've grown 2 of the same strain before and had one seed produce a huge plant and the other seed a runt; it happens, like the differences between 2 siblings.

[Radja]

Hi alltatup, thank you!
these pictures are taken when the lights just turned off (20/4). It's only the fan leaves that start with the claw tip, then it burns like nutrient burn and keeps kreeping inwards. I feeded them yesterday because it was getting worse . 5ml at 10liter (1/10 from the recommended dose,ph 6.3. Runoff the same) to see how they do.
And indeed like different siblings the smallest plant was also the smallest seed And I really hope they're not root bound because I'm a terrible transplanter

[alltatup]

Radja, read this: https://www.growweedeasy.com/rootbou...nabis-symptoms
Learn how to be a better transplanter, because you don't want all your work going to waste and you want your plants to thrive and grow huge!! Just be gentle and loosen the plants in the present pots; if they are pretty root bound, they should come out easier.

And you might want to put your plants in better and larger pots from the start, pots that are ideal for growing Cannabis (I'm a hydroponic grower): https://www.growweedeasy.com/choose-right-pot

[Radja]

Thank you very much alltatup! I was planning on buying root pouches for my next grow, but I'll transplant these then. Never considered they could be root bound because so many people are using 11liter (3 galon) or smaller for autoflowers..

[alltatup]

Radja,
Like I said, I'm a hydro grower, but I do see issues come up frequently on the forum about root issues in too-small pots. Show us a picture of the root mass when you re-pot!

[Bosnia]

Its def not a root bound , they look small for 3 gallon pot , you have a nice medium , which is peat moss based with perlite nice hydro medium to be worried for bigger pots and that mix is soilless . U can grow 3-4 feet plant in a 3 gallons with nice medium , check the pictures on internet from commercial growers the newest trend is growing a big root balls in nice medium , root bound affects mostly compact soil/dirt mediums grow organic. If u use any nutritions at least one per week , there is no nut deficiency ,it looks like phosphor . I guess you are indoor so temperatures are ok . Overwatering it may be ,stop watering them with runoff try with small amounts of water so they will dry everyday . People often forget that some genetics and phenos are just week ....

HELP stunted growth yellow curly leaves sickly plants! Pics included

Hi and thanks for reading! I've been a lurker for some time and haave learned a lot over time, but am now having a problem with the last few grows all going the same way. this is waht happens:
sprout seed, put it in one of those little brown pucks you soak in water and it expands, i think it's peat? 5 gallon pots, plenty of drainage, all seeds are female auto's from a reputable company and I buy from different procducers also.
it grows great, then they all end up like this:

stunted growth messed up leaves, barely any buds, very sick looking, they ALL do this. Prior to the last few grows I had beautiful halthy plants and buds, no prolbems at all. My room is 4x8x8 I had 6 125 dual spectrum CFL's a carbon scrubber with a 4" inline fan with 280CFM drawing air outside and an oscillating fan. Thermostat in house is 73, so room is a little warmer maybe 5 degrees? not postive but it's not burning hot I don't think. I only use Roots Organic green camo bag soil, and was using clean filtered pond water, but then switched to tap water that I let "breathe in open containers, the tap water pH is 7.4. I use a soil tester to test moisture and pH also.

I recently switched to LED's over the top, 2 450 watts units (VIPARSPECTRA) side lights are still CFL's 125 watts and are about 18" away from plants, the top LED's are about 22-24" away from plants. Again, I was getting great results earlier,,,, nothing has really changed that's why I'm here

too much nutes? too hot? too much water? lights too close?

I'll be switching over to all LED's soon.

Thanks for any and all input, I'm anxious to see what you pros have to say!

[alltatup]

z13, hello;
You changed your water source. When you prepare your nute solution, what's your pH in and runoff pH?

[Colombo]

Welcome to GWE z13 ! A couple questions if I may. 1) were the plants condition ok PRIOR to the addition of the led lights ? 2) The soil tester is it a two probe for light, moisture and ph ? 3) do you feed your plants and 4) do you ph test AFTER adding anything to your water/feed as well as runoff to 6.5 ?

[z13]

Thanks for the quick reply! alltatup, I changed the water source b/c I thought that might have been too nutrient dense, I also DO NOT use any outside or extra nutes at all, just the Roots Organic camo bag. I'll have to check the pH of the runoff today. pH of the soil in general is right at 7 and stays steady. Colombo thanks for the warm welcome! answers to your queestions:
1. the LED's made no difference, the plants started doing this before I swapped the lights, i just got tired of the cfl bulbs crapping out so fast.
2. The tester is a double prong for all 3 yes, moisture, pH and light.
3. They get no feed/nutes at all other than the Roots Organic soil in the camo bag, and I don't add anything at all to the water. Just plain tap water left out to breathe and the soil.

lights are on dual/full spectrum like they have been since I started, on a time of 20 on and 4 off which again, in the beginning 4-5 grows worked perfectly.
I will test the runoff and see what i get in both those pots and report back asap. Thanks so much!!!

[alltatup]

z13 Temperature is a serious problem; I invested in solar panels a couple of years ago and got a good chunk of my money back from govt. I also switched from HPS to LED (I have two grow boxes). I figured I was gonna do it right or go broke trying.

The LEDs max out the grow room temp at around 73, which is a huge improvement over how hot it used to get in there. Each grower has to work with budget, environment and various other circumstances in order to get it right, but I figure that having better harvests because of properly tuning in the grow room environment will ultimately save money.

[z13]

yea, that's why I switched over to LED's, I'm just surprised they are running hot, I have to check and make sure vent to outside is clear, the inline fan is new, and so is the scrubber, and the fan is almost twice what I was running before, weird.
Thanks again so much for your help! We'll see how things go next

[Colombo]

I run 2 300w LEDs at same time and average 73-75*. I have a 6" intake at floor level forcing cool air in and 6" pulling out hot air at the top. The highest temp was 82 in summer until ac came on and back to 73-75* temps. If you have a crawl space, that's always cool air you can harvest. If you have room a Bucket of ice works in a jam.

# of Plants - 4 (FEM - Blueberry, BubbleG, Zkittlez Glue, Obiwan Kush, Wedding Cake)(Issue is with Blueberry)
Grow Type - Soilless (1:1 Vermiculite + Peat Moss)
Grow Stage - Seedling
Bucket Size - Solo cup (has 4 holes for drainage at the bottom)
Lights - 2 combo T5 Lights (6500 + 2700)

Water - Distilled water only
PH - 6.5
Nutrients - None added

Room Temperature - 20-30 Celcius (68 to 86 Farenheit)
Room Square Footage - 20x40 humidity tray + dome

Pests - None known

May 10 - Soaked seed in shot glass for 24 hours.
May 11 - Moved to paper towel + plate method (on heat mat + in humidity dome with both vents open - 50% humidity)
May 15 - Tap root is about 1cm, moved to solo cups, watered cups until 10% run off which happened very quickly, planted seed ~0.5" - 1" deep, misted the top with water, turned on T5 lights(18 hours) above 7" humidity dome.
May 17 - First sign of seedling, misted soil to keep moist.
May 18 - Seedling + shell out of soilless mix, misted soil.
May 19 - Taller seedling, shell still on, DID NOT mist soil as it felt moist.
May 20 - Fell overnight. Removed humidity dome and brought lights down to 2-3" away. Still down in the evening so I removed the shell manually easily. Turned T5 lights on 24 hours.
May 21 - Still down and looks to be dead/dying.

- Note that the soil looks very wet but that's because I take a picture after I've misted the base of the soil.
- I misted the base of the soil with water daily but never lots of water to see a run off.
- Soil is still moist.
- 3 other seedlings not showing yet.

hi InSaNe

It's not a good idea to sprout the seeds together in the same pot; it will cause problems when you try to separate them.

Your seedling looks quite stretched out; she needs more light. https://www.growweedeasy.com/how-far-grow-lights

[InSaNe]

alltatup Seeds are in separate solo cups and were all growing their taproots in their own plate.

[alltatup]

InSaNe My bad!! I looked at that pic and I saw the seed shell in the background and thought it was another seed coming up!!! Blush blush.

[InSaNe]

Thanks for the tips Colombo, haven't misted since the 20th, hopefully some real sun light will help it tomorrow.

[R4st4m4n]

Noticed this 2 days ago, plant is about 1 month old. Is this Nitrogen or Magnesium deficiency?!

plants are indoor. Fem white widow

already changed to N supplement, seems the spreading stopped

any help guys?

[Colombo]

If the spreading has stoped give them time to recover. Do you PH water at water/feed to 6.5 in and out at runoff ? What soil, nutes, lights, feed/water schedule?

[dingdong1]

Leaves turning yellow and curling up, im really worried, im using super soil 20,20,20 1,200 watt lighting.
Please could someone help me?

[Colombo]

Welcome to GWE! Do you just water or water/feed ? How often, how much? Do you have mushrooms in the soil? Type of pots, plastic or fabric ? who made the soil mix ?
