Yep, only dark green leaves which initially made me think of too much Nitrogen.
What is the soil you are using and have you checked the runoff ph?
Run off was 6.7.... the soil is a mix of super soils augmented with worm castings, peat moss, and a little coco coir. 2 out of the 4 plants are really loving it. The 3rd is the one in question, and the 4th was a bad seed (i think) almost stopped growing after day 3.... it is catching up but looks like a bonsai tree. But i suppose if the issue is soil then its problems might be connected.
this makes the most sense, in my case I think heat was the trigger at the seedling stage. There was a heatwave.... as long as it isn't insects, she can go back in the tent with the others and we shall just see what happens. small yield is still better than no yield.
Seem to look like wet damage. Heat, moisture from spraying old water.
What they look like the brown on top is propagator damp type damage. Leaning against the lid in an hot prop wet moisture constantly on it
You know I rewatched shantibaba podcast this week he said when he finds genetic problems he actually flowers them just for scientific reasons. When asked about the modern phenomenon of the diseases in cannabis recently.
