Hey Growmie,
I'm an avid believer of defoliation, but I wouldn't advise it at this point just to make sure you prevent stress during the flowering stage. If you were going to do anything like defoliation, trimming, etc ... you should always do it before Week 3 of flower so no stress is induced. Hopefully, I answered your question and remember "Happy Growing" and "Free your mind one puff at a time"
