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 !

Please see the 2 photos marked in the diary. Is this a classic PK burn? Did a feed with no MegaCrop, no cal-mag, just PK boost at diluted dosage. The coppering and yellowing has come sudden. Leaves are crispy where burnt. I hear its easy to burn with PK boost. Did I do that?

Yellow leaves with grey/dark outline
I have some yellow leaves with grey/dark outline. Do you know the cause? Could be the humidity level too low? or K deficiency?! I'm not so sure about the last one. Help me guys please.

Black growth seedling
One of my 10 day old purple punch seedlings has some black stuff on its new growth in the center. My older PP had it too and she’s big now and doesn’t have it anymore.Still is this anything to be concerned about?

These three girls are all wilting and/or barely growing. I'd say over-watering except I've only been giving maybe a quart then waiting till the soil dries a little bit. Not too much tho. Could it be a nutrient problem already?

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.

Organic peat control
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?

LEAFS DYING
The edges of the leaves are dry and black. Every single point of the leaf is burnt(black) or yellow...even some edges on the leafs of the coal are burnt. I guess it’s overfert...but I just flushed. Is it Ph? I haven’t checked in awhile. Is it they ready to be cut down?

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?
