Hey, buddy! 👋
I wouldn't recommend defoliating autoflower! Especially since you're already in the flowering stage, and defoliation will just slow things down! Right now, the plant needs its leaves! They act as batteries and storage for the nutrients that the plant will soon start transporting to the flowers! The flowers will grow more actively if there's foliage around them! 👆
I don't recommend defoliation in your case, bro! 👆
Good luck, my friend! ✊😇
