There are only two reasons you would want to defoliate - to get more air flow through your plant or to get more light to lower bud sites...
I don't see that you have much of a problem with either one at this point... but if you feel you do, do the defoliation slowly - i.e., remove a few leaves and wait a day or so to see if this has stressed the plant out... if everything is fine and it's either not been affected or it has bounced back, and you feel the need to do more, then you can go ahead...
Good luck!
Please click on the grower's name that is answering your question to see their profile. There are fake accounts being created to look EXACTLY like real accounts - but they're easily identified by doing this... at this point, it is only myself and m0use who have been affected.
