Wrinkled leaves- Mosaic virus? Overfert? Mutation? Sodium ? pH ?








Three types of plants - and all are affected:
N.lights from seeds, Lemon Kush from seeds & different supplier,
Blueberry/Hawaiian 3rd generation clones.

Worst affected are the younger, the smaller, and the runtish plants.
Least affected are larger ones, with the males ( largest) almost unaffected.

Here are the suggestions from many many sites and posts:

SALT in the Coco- dont think so, Its a good brand that makes
a big issue about having been washed by 3 monsoon rainy seasons.

VIRUS, mosaic, tobacco or cucumber- photos of virus in cannabis that
I have seen have very bright yellow veins and mottled yellowish discoloration
on leaves which I dont have. ( but maybe those photos are not virus !)
Also it is said that virus cannot be transferred from seeds.



MUTATION- from D J Short etc - no, too many varieties affected.

OVER FERT- was running a bit high, but flushed twice 10 days, and again 7
days ago and reduced feed to 400 ppm but young leaves are still wrinkling.

pH- maybe ? I have been using GH test drops - hard to judge the color
accurately but should have been in the 6.0 to 6.5 area.( ordered a digital )

Sodium Benzoate- a preservative- leaching from plastic containers.
Maybe. I'm using a large plastic drum from an ethnic food store for 1st time,
as a reservoir.

Details : All in Coco + 15% perlite, 2 inches hydroton in bottom . Lucas
formula from start, now in 3rd wk of 12/12, under 600w hps. Watered as
indicated by moisture meter- once every day or 2 days.Drain to waste.
Some 'adult' lucas was used on seedlings/clones by mistake for a week.
Reservoir is aerated for 2 hours before feeding.

Thanks for any comments , ideas , or thoughts on this problem.

THC, if you had to vote on it, which do you think is the cause ?

I dont think its over watering - when I culled the males I examined the coco - it was quite moist and the roots looked very good.

Anybody - a wild idea, a guess ?

Thanks !

i have a plant doing the same thing, i was thinking its a mutation as well. Not mosaic virus for sure. I treated mine with a systemic insecticide and the weird jagged shit started. I'll snap a shot for you so you can compare. Looks identical to me though.

i'm interested to know what that is also. i had a cut of G-13 that looked exactly like that. It never transferred to other plants like yours, though.

What's the tempearature and airflow like in the grow? Looks like something in the feeding schedule for sure too, did you treat the coco before using it? Is there any perlite or drainage medium mixed in? Can you give more details on the growroom and the nutes etc

Bali - mine are not going yellow (yet!) but the deformation/crinkling looks very similar to yours. I dont think cannabis is that different from other plants and when other plants get a virus or fungus it attacks part of the leaf and spreads. Some parts of the infected leaves look fine. This is not the case here with mine or yours. Its all over every leaf. Did you use that hormone B1 thing Superthrive ?
I did for the first time with this grow.
Thats on my suspect list now.

MoldyDreads- Temp has been comfortable southern 70s , fan blowing on lamp- good circulation and extraction. Ive cut off the fan as its been said that curling leaves can be a reaction by the plant to excessive moisture loss. Humidity is about 50%.
Did not treat the coco- wet it with pH adjusted water, mixed with 15% perlite and 2" of hydroton at bottom of pots.

PistilPete- what happened to your plant ?
Please tell me it survived !

Thanks for all thoughts.
