Is this a Male plant?

[HobbitGDF]

i think so

[Tofasgt]

Hey guys, first post and also first time grower. In need of some help here.

The setup:
2xP1000 Viparspectra (22 inches above plants canopy)
Vivosun 6" exhaust (vented to the outside of the garage)
Fox Farms Happy Frog soil
3 Gal pots
2x hurricane 6" fans
homemade 4x2 grow box (2x 14x6 intake vents at the bottom)
plants are 4 weeks old (roughly)

I have the Fox Farm trio nutrients mix, but have only watered with the Big Bloom mixed with Cal-mag once (1 1/2 tsp cal-mag with 1tsp FF Big Bloom in 1 gallon of water pH'd at 6.3) the rest of the grow I have only used distilled water also pH'd at 6.3-6.5. Recently I've noticed the lower leaves tips turning brown and rolling backwards. Yesterday the lower leaves started turning yellow/brown. I'm guessing it's a deficiency of some sort but looking for some help identifying the deficiency and how to go about correcting it. The grow box stays around 77-79 degrees and around 50-55% RH. It seems like all growth has slowed substantially if any at all the past week. Any help would be appreciated. Thanks in advance.

[Puglover1]

I haven't looked at the GWE pics for your issues. IIRC one tsp equals 5 ml? I've never used more than 4-5 ml of Cal-Mag in a gallon of water. Not sure if too much of that does this. I don't use distilled to water the plants.

[BU2B]

EDIT: First if these are Auto's please consider Private Messaging Canuck147 or follow his posts. He's an Auto guy with a good deal of experience and knowledge.

Okay - I'm going to try this again (my internet has been iffy at best since last night and I've tried to answer you a few times).
I don't know if your Fox Farm soil is hot so this may be all for naught but here's my suggestions:
* Flush your growing medium with 3x the volume of liquid (i.e., 1 gallon pot = 3 gallons of water) Flushing liquid should contain water (ro or distilled if possible) ph balanced to 6.0 and with 2tsp of hydrogen peroxide per gallon.
* First watering after Flush make sure that your growing medium is dry or barely damp to at least the first knuckle on your index finger (2nd knuckle is better about 1.5 - 2 inches). Your first watering should contain 1/2 the amount of recommended nutrients AND 1ml per liter (or about 1.5 tsp) per gallon of CalMag or MagiCal
- UNLESS your soil is hot - they should be getting nutrients on a regular basis
to be quite honest Tofasgt they DON'T look horrible and your being very attentive - I'm sure your girls will be fine, but please; keep us updated on your progress. Happy Pharming!

[Tofasgt]

Thanks again BU2B I absolutely will give this a shot. And they are not autos, just some regular ol photo seeds from a bag. I will do exactly as you've mentioned here this weekend, I just fed them last night as suggested by a couple other people, switched up a couple things and gonna wait a couple days to see what the new growth is going (if there is any new growth) as growth has seemed to be stalled since this has started. Thanks a ton.

Hello again - I have a question about these cheap grow lights from Walmart that I am using. This is my first time growing. I have 3 of these Bulbs which I bought from Walmart in a rush. They seem to be working well for my seedlings at the moment but I was wondering a few things:

• Will they be good enough for a single plant?
• From what I can tell they seem to be in the right spectrum for growing Marijuana?
• since they are 60W Equivalent should I think of the setup as 180W total or somewhere in-between 60W to 180W?
• I am not sure what "60W Equivalent" means. Are these really just 8W bulbs "60W Equivalent" is marketing?
• Will the three bulbs be good enough for 3 plants but perhaps give lower yields? I mainly ask because the site seems to only mention 100W+ bulbs

The three bulbs are mounted on flexible stands so I am hoping that during the flowering stage I will be able to spread them around the colas and perhaps in between colas if there is enough space and the plants don't get burned.

My plant also took some damage but it's recovering now - should I snip or keep the two leaves at the bottom? see photos here.

Many thanks

[Puglover1]

Hi. Yes remove on bottom cotyledons and first set of true leaves, they're dead. Your bulbs seem more for cannabis germination. I won something like this, I put it in a round plastic hanging lampshade over one plant, it grew up but before flowering time I bought LED/blurple panel lights. I've upgraded since. Light matters very much. This grow bulb says 100W but in the 2nd pic it says 30W which is probably it's true draw. I looked at a true 32W on Walmart, it just didn't look like mine. Not sure of my lights specs ATM, too lazy to go look at the box, sorry. I'll post a pic of my first 3 plants before I got panel lights, it shows the light & shade over one plant. Seeds were not started at the same time, bag seed from dispo weed. https://www.walmart.com/ip/Energy-Sa...ll&athena=true

[Puglover1]

Pic of when I first moved them into my closet, and the 1st seed - all indica - that grew under the hanging lampshade with grow bulb like one I showed you above. Lower leaves weren't going to get much light. In the end, with two LED panels and much advice from this site I could hardly close the closet doors, nice first harvest. Three plants = > 1lb. Lampshade w/black trim in upper R corner is what this plant was growing under.

[xianate]

Thanks! I did some research and found that when they say 80w equivalent it means its as bright as an 80w incandescent bulb but with a lower actual power draw. Still not sure how this will affect the plant but I will do some more research later I guess. Thanks for sending over the pictures. that yield is not bad at all for the bulb. I will probably get some more heavy-duty lights once my plants have grown a bit more or for the flowering stage. I have 6 seedling growing now and have no idea what is going to be male/female yet so I guess it depends on how many males I throw away.

[Puglover1]

That yield was from two KingLED 1500 panels. Watch Amazon for prices on panels, they had good deals on nicer lights in July. Look for full spectrum, not bluple, if you can upgrade.

Help please! Super dark edges around leaves after flowering started.

This is my first time growing and my plant hit the flowering stage around August 11th. Around 3-4 days ago some leaves on my plant have developed very dark edges out of nowhere. I’m not sure if this is normal or not. I have her in a 20 gallon pot outdoors and am using Vigiro All-Purpose potting mix. When watering, I wait until the entire top 1 to 2 inches is dry and water until just a small (maybe 6 ounces) of water drains from the bottom. I am using the felt-like material pot so drainage shouldn’t be an issue. Any help is greatly appreciated.

GonzoNeko.

[GonzoNeko]

Puglover1 I wish I knew. Someone gave me a bag of shake and I found a few seeds. I ended up with this one female and that’s where I’m at.

[Gingerbeard]

I'm seeing spider mites. Picture 3 is lousy with them.

[GonzoNeko]

Gingerbeard oh I heard those are a notorious pest for plants, but I never knew what they looked like. Thanks! I’ll have to figure out how to rid myself of them without harming the buds.

[BU2B]

GonzoNeko
It looks like the start of manganese deficiency. see post #516.4 above only for first feeding add 1tbsp epsom salts per gallon instead of cal/mag. Not sure If I'm seeing white powdery mildew but I'd remove the leaves beyond repair. I would keep looking if it was me - but give this a try. Best Wishes.

[GonzoNeko]

Thank you for all of the help so far! I’ve already DM’d somebody from the post you referred me to so hopefully I can save this girl.

[Gingerbeard]

BU2B Why is everybody always afraid to agree with me?

[GonzoNeko]

Gingerbeard Cause spider mites are harder than nutrient deficiency’s from what I’m reading 😭 .. hahaha

[Gingerbeard]

GonzoNeko per your post 519.4...
Based only on the buds you've shown, it might still be early enough to try a treatment not recommended for flowering plants.
I am able to watch my plants close and often enough to be obsessive. The two times I had to deal with them I plucked what I saw and used a solution of 2 teaspoons of apple cider vinegar to a quart of water as a spray. The spray is my experience. Others have had the same experience and others have had bad.
Folks are going to turn you on to all sorts of products. This is a good resource.

[GonzoNeko]

Thank you! I’ve picked the leaves with spotting like that in the pic you called out and will be looking through the post you provided. I’ll try out your spray before the buds thicken further.

[Growercz]

Hello a need some advise what are those sacks is it hermin? And i grow only outdoor this is my second time

[Rwise]

Could be seeds or fat lady parts, pluck one off and dissect it.
Welcome to GWE

[Growercz]

**Upper leaf near bud showing rusty dot

Hi there,

Newbie first grows, as usual, experienced nut burn, been flushing adjusting PPM around 1,000-1,300.
Don't mind the burnt edge that's caused by nut burn, but not sure why after flushing the leaf tip still bends down.
Also, the leaf tends to get pale green not sure what is missing.


I am in a place where I have limited access to the individual types of nutrients.
I can only purchase a premix nutrients bottle.
I have one with N, P, K
Another one with NPK 15-15-15=45%, Ca.Mg.Fe.S.Cu.Zn.Mo.Mn around 8%.

I'm growing with organic soil so I think the micronutrients are covered.
Not sure still showing the rusty dot in the flowering stage.

My guess could be some of the micronutrients lockouts.
Not sure what caused it.

My setup is below.
1.5 x 1.5 x 2m tent.
Lighting with 400W LED lighting for each cannabis plant.
The LED light is close to the plant, I have an iPhone app with Diffuser covered, showing 900 PPFD on my cannabis, I think it's not a heat burn.
My room is always on A/C at around 25 degrees C.
I am planting 3 different strains, one is wedding cake, one is the breeder's gift not sure what it is, the last one this one showing here on the picture I believe it's OG Kush.
I've made such silly mistakes having them experiencing nut burnt for all of them, however, the wedding cake and the breeder's gift were recovering nicely after flushing.

Only this OG Kush is having too strong nutrients even at Veg stage they were showing pistil, even worse after flipping the switch, at flowering week 1 for this OG kush is already full of pistils.

I suspect that the nutrient is still burning the plant, or the burning is causing the micronutrient lockouts.
Should I flush them again and add just P to my cannabis for flowering bud purposes?

Or if anyone can help to identify the problem, I much appreciate your help.

Thank you thank you.

[SoOrbudgal]

Answered your own question. You need alittle dose of N whislt in flower but PK is the minerals they need more during bloom. If you already just watered ( no nutes just water ) i'd let it dry then use Epsome salts i use 1 tbls per gallon of water. Rinse the roots with that, allow to dry and see if within a few days if that does not stop the issue.

[Askdog]

Thanks for your reply, so meaning that I mix Epsome salts with a few gallons of water to rinse it off all the nutes, leave them to dry with no nutes at all for a few days and see how they react? If the burnt mark not increasing I would add back little N but more P & K for it, right? Do I need to dose them with the Ca.Mg.Fe.S.Cu.Zn.Mo.Mn bottle so they have all the micronutirents? Thank you. I assuming the Epsome salts is with magnesium & sulfate help the immobile upper leaf?

[Askdog]

Oh oh oh, right that makes so much sense to me now as I just realize at the flowering stage they need more Magnesium & sulfur, I just spotted that my wedding cake and the breeder's gift is also having slightly yellow dot in the immobile leaf, I got it, Epsom salt is arriving tomorrow and let's see how this goes, will update in a week to let you know the status, thanks Man!

[wikimania1975]

I am beginning to struggle with my first grow. So far it has done well but it is now starting to lack things that I dont have a well enough knowledge of. Any help is advised. I'm using a marshydro ts600 led light. Using general hydroponics three step nutes. And watering only when I think they need watered. So i could be underwatering. Idk lol

[BU2B]

I think what you have is a magnesium deficiency. Please look here -> How to fix Cannabis Magnesium Deficiency (Mg) Pics & Symptoms (growweedeasy.com) or here -> How to fix Cannabis Manganese Deficiency (Mn) Pics & Symptoms (growweedeasy.com). Overall your girls don't look bad, but I would do a bit of reading and comparing before you settle on a course of action. Happy Pharming and keep us posted on your progress. Just a side note - If you plan to continue with your indoor grows it might be a good idea to invest in some cloth/burlap growing bags that will allow better root respiration.

Excellent chart

[mande1991]

I started my grow a couple months ago and everything was going well enough. I have a 4x4x3 grow tent. I live in an area affected by the recent hurricane and lost power for 10 days. In order to make due (with light cycles) I had to put my plants outside during the day.

ONe day, while at work, it rained a crazy amount while the plants were outside. After that I noticed one plant starting to look unhealthy and presumed that it may be a case of over watering, in which I tried to wait on watering to see how it fared.

With no change, I've since watered it once. I wanna know if I could rehab this plant or not and what the issue may be if not. I have 3 plants, total, one is still thriving; this one pictured is struggling, and another seems to be getting sick (the same way the other did.). I have power, now, and have returned them to the tent but I'm worried I made it to the flowering stage and may have lost 2 of my babies. I used seeds that I've collected, so I couldn't even try to give a strain. I'm open to all help. Thanks.

[Puglover1]

Did you look on the main GWE site at the leaf problem identifier? What soil, size pots and light watts are you using? The rain might have flushed out nutes.

[mande1991]

I have looked at the infographic but by the time I had reliable service to compare, my plant looked to be a bit too far gone to identify with surety.

Im using 2 300w led and 2 200 w led to supplement, 5 gallon pots, fox farm happy frog soil. All of that was keeping the plants looking great. The rain, humidity, or change in lighting source caused the issue, I'm just not sure what the issue was to try and fix it. I'm pretty sure one plant is donezo, one is struggling, and one is still thriving like nothing ever happened. Assuming the one that's thriving is just a resilient strain or that since it was less leafy, the moisture didn't attack it the same.

[Organicpufflife]

The plants in my flower tent are showing symptoms and I don't know what it is... At first I thought it was nutrient burn but is weird because I've been giving 1/3 of the nutes.. can someone help me identify what Is wrong?

Details:
Light Cycle : 12/12
600 watt HPS
Organic grow using biobizz Nutrients and compost teas

I think she needs calcium Look here -> https://www.growweedeasy.com/cannabi...ium-deficiency

[TSR]

American Pie Auto 2 weeks into flower exhibited this spotting last night when I went to water. Originally thought it was septoria, still may be, but looking at another leaf this morning started to think it may be something else. I have 4 plants in a 2x4 tent under 300w lamp, 50-55% RH and temp around 78. I removed the affected leaves thinking it was septoria, but figured I’d ask here as I haven’t come to a conclusive answer as to what is going on. THANKS!

[Johncena]
