One new top leaf is wrinkled too, so I would go with bad watering regime and overwatering . Pots has to be light before watering them again. All the Best !

In the 3rd photo in week 12 there is spotting on the leaves. Does anyone have an idea of what that is from? A deficiency? I had trouble getting the nutrients right and that showed up first after I flushed for a few days.

Grey leaf tips
Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?

Black marks on leaves of a slow grower.
Noticed there's black markings on the edges of the leaves on our slowest growing plant. My initial thought was water droplets sitting on it before it had fully broken out or could it be something else?

Leaves burn
Hi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips. I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?
I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc. I believe this may be nutrient burn? Added an old image of leaf before mainlining, the plant is 1 week old after mainlining was done.

My seedling doesn't look so good.
This is my first coco grow so could be possible that I made a mistake. The other three seedlings are super healthy but this one has this weird thing with it's leaves. Somebody seen this before? I gave them some root juice and fertilizer before transplanting with ph between 5,5-6.

I think my plant is being eaten but gnats and it looks like nutrient damage on it but I haven’t given ANY nutrients to it. What should I do? Can you diagnose my plant? Any remedies? I heard cayenne pepper can be used for a pesticide is there other things? Does Neem oil work well?
