first grow

hello all! they aren't much to look at. but they are mine. learning as we go! need to invest in a ph Meter/kit as I hear that's pretty important.
Anyway. for medium I'm using coco from happy frog. for food I'm using buildasoil buildabloom as we've switched to flower. they are only 5 days in.
first image is pink runts. to me it looks like a nitrogen Def which I've addressed with some top dressing of worm poop.

ATF is the second, and she has burns from my over using neem and too high of light. her leaf tips are slightly curling down,which I'm hoping is just wind burn and I've turned my fans down.
