Blackening leaves on 2 week old seedling.
Any ideas what has caused the blackening on the leaves? More effects of the overwatering? Hope it's not a lost cause but I'm losing hope.

Black spots under leaves
What are these black spots? I recently released some ladybugs in my grow room and saw them crawling on the plant this week, so is this possibly from them or from something else?

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.

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.

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?

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?
