Not an expert but I think your soil may be a little hot based on the tacoing and wrinkling of the leaves. If your feeding them nutes maybe a little to early or to much. Nothing to serious they are alive.
Looks good so far. But without knowing more the only thing I see is the moisture in the soil. If you just watered before this photo that would explain it, but remember, cannabis is not a real thirsty plant. A little water goes a long way.
