you only need take off the fan leaves (biggest leaves when they start to shade budsites underneath).
...Actually..IMHO, removing large healthy leaves can never be healthy or productive for a plant. The leaves are 'vital' for photosynthesis, for transpiration, and for moving/transporting water and nutrients throughout the plant as needed.
"I" don't believe pistills and small budleaf benefits as much from the direct light, as do the large fan leaves, nor benefit the plant as well.
I do think there can be some benefit by "skirting" or trimming some of the lower growth from underneath the canopy. It won't recieve the needed light to produce quality buds, and allows more resources to be used at the canopy, where light is abundant.
...not 'dissing' your growing ability or advice pkj, just a different perspective on the matter.
