This is my first indoor grow, and first I've payed close attention to. When do I need to start pruning the water leaves?
Some people prune extensively, some people don't prune at all. Its a very hotly debated topic on GC. Personally I just let the plant do its thing and remove leaves AS NEEDED, meaning whenever they are dying or shading a bud spot. Even then, I try to bend the leaves out of the way. Good luck
