Looks like clones in rock wool in coco. How hot is it in there? They look hungry. How long did you acclimate those cuts before you put them in there under that light? Are you feeding them? What’s the humidity in there?

Yeah some of them look real hurt. How have you been putting fluids on them? Looks like a lot of light burn and low nutes.
