Whatever you do, please don't defoliate for the sake of your plant.
It needs every leaf it has to be healthy and have a correctly functioning metabolism.
Removing the leaves is more likely to make your buds swell with excess nutrients, not decrease their content.
Concentrate on doing a proper flush and nutrient after taste will not be a problem.
The theory about removing leaves to clean the buds is some seriously flawed corn flake packet "science", it is just not possible.
