Hi. I don't mean to be rude or unkind, but this does not look like a very successful setup for the size and (I'm guessing the expense). I think I am on track to get more buds from my 3'x3' one Bubblegum plant under a single 600w MH. I suggest you train the plants to have a level canopy. Also, these plants need more leaves to take advantage of that beautiful diffuse light you have got going. They are the food factory of the plants. I generally just take yellowed/ing leaves out to keep the microclimate in the heart of the plant from becoming humid and pest/disease prone. Best of luck with it all, Jack.
