hello 👋
Yes yes yes. I recommend defoliation at day 1 of flower and week 3 of flowering which you're in. Clean up the bottoms (lollipop) it'll get rid of popcorn buds and boost the top colas. Remove all leaves and bud sites at the bottom 6 or so inches.
As for defo on the upper part be a bit more gentle, maybe just a 10-20% and mainly leaves blocking the light. 👍
