i prune for light, but i almost never remove the whole leaf.
i cut the outer "Fingers" untill theres only the 3-5 central leaves.
it leaves the largest surface area but lets more light hit the central mass.
id have to know how busshy it is, but mostly i just tie mine around.
i say around cuz my shit has to fit together like a puzzle, little bonsia little weaving, little wire goeas a long way
