OK, I'll probably hold off on cutting the leaf.

I did have something weird happen with one clone. The main growing shoot somehow shriveled up and basically died. So now one of the other stems became the main growing shoot. It was kinda like a "self-topping". I have no idea how this happened! I thought it was some kind of nutrient issue, but I don't know. So, I cut off the dying/shriveling grow shoot and hopefully it'll just be the same as an early topping.
