I don't see any leaf-curl, so if that's a sign off too much sun, my babies are fine. I water them every day, they are in well-draining soil, and of course the vast majority are in clay pots, helping them to dry out a bit faster. All-in-all, KD, I guess they are doing fine. Perhaps they are just worn out from growing so fast at the start of life and they are resting a bit now.
