tie that bitch down. I did last year when mine was about that height if it's rooted in the ground solidly you should be ok. I tried lst, FIM, and just topping. FIMing is where it's at IMHO. but it's to late for all that really. Just pull it down a little at a time, don't do it all at once go out there every few days and pull it down until your happy with the height or you feel the plant can't take any more bending. It worked for me. Good luck, and she looks good man keep up the good work.
