Hello Growers! I’m just curious of what causes this curling or waving of the leaves. I do notice it only happens during the first set of true leaves and they grow out of it. Is it due to my environment or medium? 50%RH 72F and 350umol PAR. It doesn’t appear to affect growth.

I've think I've pinned this down to humidity, usually goes away when I put the bell back on it. Also, I run my seedlings at 250 umol, might be too many photons based on your DLI ( hours of exposure in relation to u/mol).

I put back the dome back on and gave them a couple of spritz. Seems like they responded fast! It seems they grew faster and look a little more green within the 24 hrs. Right on Thanks!

Raise your light a little, try another inch. I try mine till they reach or "pray" for them when they're hungry. It's all about testing and learning. 👊👍
