Its about week 2 on my plants and just the other day the leaves on plant 1 started drooping a little, The leaves on plant 2 are fine but that one has like a weird wavy stem and plant 3 started droopin too. They're green with no yellow or brown on them but they just look, depressed? Its not like hardcore curling up its like the edges are curling under slightly. I put them on 12/12 today hopin that might be the problem. Maybe overwatering? Any help?
