ohh boy here we go again on defoliation, didn't we just have this thread yesterday lol.
There is no benefit to pulling leaves off your plant at this stage, and bud sites don't need light they grow buds not leaves it dosent matter much if they are blocked by fan leaves as the fan leaves are putting energy into the buds.
There is some evidence that defoliation during flowering will produce a bigger yield and this normaly involves taking leaves from the lower parts of the plant that the plant no longer uses for photosynthesis but still suck up nutrients and water to stay alive. It is also done to improve airflow through the canopy to help avoid the risk of mold as well as letting the plant breathe better
If your looking to beat up your plant and have it be benifical id look into topping and super cropping techniques
