Defoliating this early into flowering can definitely force energy into the budsites and if you're getting limited hours of direct sunlight each day I'd want to open those spots up. Personally I'd cut away those 4-6 largest fan leaves that are sticking out off of the main stem on their own, that would open a bit off space but still leave the leaves that are attached to a branch untouched.
I also firmly believe in cleaning up the bottoms of any foliage that is in the shadows, the few times i didn't do this i ended up with a lot more tiny popcorn buds than big solid buds up top. ✌️
