Get Help for Cannabis Plants Problems as Quickly as Possible!

Hi everyone.
I have grown plants for 4 weeks and there are some symptoms appearing as follow:
- The tree seems to grow slowly.
- Some leaves below are yellowed and burned at the tip

- 2 leaves on the bottom layer are pale and black spots appear on the surface of leaves, then these black spots turn into white gray spots.
- This phenomenon gradually spreads to the upper leaves, even in young leaves
- On the surface of the leaves occasionally appears white beetles suspected to be hemorrhoids, I have treated by wiping with diluted alcohol. I didn't see any affect, so I used soap mixed water.
- The plant is watered when the ground is about 1cm dry
- I use a 100W led blue light 18/6

Does anybody know what this is and how to treat it? Thanks in advance!

the burnt tips say you are at the max level of nutrients your plant can take , the other problem is pests ,put some diatomatious earth around the plant this will kill anything from the ground , I use neem oil to spray

 

[MrBean]

Thanks for your advice. Currently, I am using tree growing soil, coconut fiber soil and Perlite in proportion (50% -40% -10%). I did not use other nutrients. How do I prevent the plants from becoming over nutrient ? I will try Diatomaceous Earth, i hope my plant will get better. Thanks you, Oldjarhead100 !

Hey guys first post, as Well as first grow. Im having some serious problems with this plant, it is at 5weeks now and it's leaves have curled since week 3, is this "hot" soil or just due to it being bag seed? Any help appreciated thanks

Help - growing in coco, started using fish shit about 2 weeks ago and then my plants started turning yellow on the tips and the spots. Also have dying leaves. Looks like potassium deficiency but not sure? I didnt change my nutes so.... any help is appreciated.

I am using a mix of happy frog and fox farms original mix for soil and their trio of Nutrients (grow big,big bloom, havnt used tiger yet) and also cal-mag I have only gave them nutrients twice. I water them about every 3 days or so, PH in the soil is 6.5~(DONT know if meter is accurate) and I don’t have a meter to meter run off (waiting for it get here ) and honestly I don’t really know what the seeds are got them from a buddy all he knew is that they were some type of lemon strain. Can I flush the plants ? If so about how much water they are in 3 gallon smart pots. The light is about 12 inches away the light I’m using is a mars hydro Ts-1000 and figured I would mention only 2 of the 4 have this problem

Thank you, Franklinmiller !

Leaves turning yellow-ish.

4 weeks into flowering in soil with a 125W CFL. First time grower not doing anything special besides bending down a couple of stems.
Could it be light stress?

I got some nutrients from the brand CANNA and got a folder to got with it. Its something like this but a bit more comprehensive

Figure its a good place for all of you with leave looking like this or that to start at. Hope it help someone!

aye guys I’m running into a little height issue with my plants they are starting to touch the light. there About a week and a half into harvest wondering if I should top the plants that are too tall

 

[FunkyButtLovin]

You need to either top or supercrop them. I would supercrop if you have the room. They're way too tall and probably still stretching.

So I keep getting these leaves with the green stripped from the middle of the plant threads.
A friend of mine said it needed calcium.
Then another friend said Cal Mag.. because you're not supposed to give em calcium without magnesium for whatever reason.


But as you can see.. it's still doing it. Ph? But that seems unlikely because I check pretty often and othet plants are mostly fine.
But multiple plants in both rooms.. led and veg state have it.

 

[FunkyButtLovin]

It definitely looks like magnesium deficiency to me.

Hey Folks. Not sure if this is a problem or not (well, it'll DEFINITELY be a problem during trimming).

Is it me, or does this MSNL Auto Granddaddy Purple look leafy?

It's the leafiest thing I've ever grown.

Here are the plant stats:

Got the seedling in a hempy bucket Jan26.

Ran about 19 days indoors under 200w LED.

After that (Feb 15ish), plant has been outdoors (San Diego, so doable DESPITE the insane amount of rain this year).

I've added three pics, one from March 6, and then two from today.

Funny thing about the plant is that it looks fucking outstanding! Great structure, really strong branches. But it's literally almost ALL LEAF!

I've brought it inside (April5) under 300w LED, as it still looks like there could be quite a lot of room for bud to come in. Plant is drinking about 5 cups of GH Trio per day now.

Anyway. Would appreciate some feedback. I suspect this plant will need at least 90 days from seedling.

Howdy from Oregon I've got fond memories growing up near little Italy and Mission dist. lots of relatives still there. Great times in the 60's. OK let's talk about your plant......if she were mine and I've grown outdoors up here now over 30yrs grew a few as a teen down your way, gardeners and me had a thing LOL " you don't tell my parents and you can pinch some bud LOL" anyhoo. First and only thing i'd do is remove all very large fan leaf even those in that center cola otherwise it looks good to me. Yep she's gonna go the 90 days for sure don't give up on her, she'll be a goodie let her go till trichs show milky get a jewlers loop. Good Luck

 

[thedartmaster]

Thanks SoOrbudgal. Yeah, love it here in San Diego. The absence of bad weather is pretty amazing.

Appreciate the reassurance. In fact, I took a look today and it does seem to be getting "powdery" in terms of trichs, and the flower does seem to be filling in. I do have a loupe, as this isn't my first rodeo.

Hey there guys! Need a little help here soon as possible please! So It’s the first time im growing and things looked normal until last week I think . I’m growing 10 little soldiers and only one of them is starting to have problems, I putt them to the soil on the 23/3 of this year and they have now 2 weeks and 4 days , I’ve been watering since the begin with ph 7.0 , but I’ve been searching for the reason of the problem and maybe ph is too high and block nutrients so yesterday I have watered with ph 6.0 (yeah I use bottled water for the moment and I just found with ph 7.0 and 6.0 ) I’m growing in a little grow box made by myself , with a cfl light with 110w. I put them to the sun at 9:00am until the end of the day (8:00 pm) and I complete the 18/6 light cycle with the grow box (I’ve started with 24h of light until last week).
Should i separate this one from the others ? I noticed today there is another 2/3 plants with one or two little brown spots on the leaves like the sick one.
