Leaf growth at this stage is minimal.
The leaves actually absorb the light energy and transfer it to the buds.
Buds don't absorb light it's the fans don't take any off.
I used to defol then I stopped and my harvest increased immensely.
I clean under the skirt after stretch and then don't touch anything.
Here is a jher was about 6 ounces of hard bud, I make concentrates with larf and trim.
So I don't mind a little extra.
I like em bushy and natural.
Just my preference but I have good results by letting them just do there thing.
I do top young and LST though.
Stay safe
