Hey BlueRaincoat! Yes at this point you can defoliate if you need/want to just be careful when doing so to not take off to much or any potential bud sites as it can affect yield. You can also try to tuck or bend some of the fan leaves out of the way to let some light through. or do a mix of both defoliation and tuck/bend them away and you wouldn't have to take as much off. Hope this helps Happy Growing👊
