so I think I may have over watered them. I'm growing in sunshine advanced mix #4 and hit them with roots organic nutes once a week. Some look great and some look like below
They do appear to be overwatered to my eyes. Let them dry out for a few days, and then start watering lightly. Seedlings need very little water at that size.
I agree they are looking overwatered also what is the humidity looks like ur leafs have some twist and deformation
