Hey buddy. I agree with you, u need to do some defol. It's not a optimal window to do defol in but you'll get away with it. Blindly no no. What you wanna do, is grab a node and do it node by node. Each bud site on the node will have around 3/4 sugar leafs/fan leafs. What you wanna do is go round it and take 1/3 -1/2 stick to more to the 1/3 of fan leafs. Focus mainly around the top and leave allall fan leafs sugar leafs that are at the end and aren't blocking any light. If it's not blocking any light then there is no reason for you to take it. Main reason to defol is to get light to reach the lowest ends of your canopy so there is no need nor call to defol leafs that aren't blocking out light or if you can get away with leaf tucking do so. If u want a more detailed or help in any way feel free to DM me. Good luck.
