I have an issue thats not really a problem. But have no idea whats going on. Some of my plants have super dark almost black leaves that feel like fake plastic leaves mostly towards the top of the plant. And where these leaves are the buds are huge and super dense compared to the rest of the plant. So it seems like whatever issue it is, is actually something that this plant loves. The mid to lower leaves normal. This is a strain thats unknown. Clones were given to me from a friend who doesn't have this issue and his plants don't have buds nearly this size. I grow in coco. Feed 3 times a day. House and garden nuits. 72 plants. 6 1000 watt DE. 3 different strains. Other 2 strains so zero sign of this. So I'm at a lost.
