That doesn't look like a bush monster yet. How far into flower is it? and how much more room do yu have for upward growth? Don't do any cutting at this point, she is rockin and yu don't want to disturb that. If yu are afraid of running out of room, yu can tie strings to the upper branches and gently bend them out and down several inches, this is the LST method and it works quite well, and it will allow more light to get down to the lower buds which will help them plump up. I had a jungle in my last grow and they were all up in my lights. I had to litterally "break" them over to get them out of the lights. Some I was able to tie down while others had to be broke, but they continued to grow and produce right to the end. Big Bud mojo to ya
