the leaves on 1 are curled under(1st node) also yellowing and now with grey spots, a purple vein in center of leaf. others arent curling under but are turning yellow w/ gray spots. growth is really slow for 24/0 schedual.

Younger ones are still working on their first node and have nice deep green to them but the few that arent im concerned about..

Im using happyfrog soil in 5-7'' pots, wqatering with tap water every 2-3 days. Im curious if there is a milder soil out there for seedlings. is that even my problem.
