Pruning

If I remove all fan leaves from the plant at any stage of its life, but specifically a month into vegging will it shock or impair growth to my girl?

Whats your motive?
Pretty much a dumb idea overall, but I can see a reason or two, but none that would 'produce'

yeah it will slow the growth so you can fit more in a small space.
is that what you want cause thats what you get?

The only time I "trim" is from seed.I trim the big fan leaves from the main stalk,when I start the 12/12 schedule.

My reason for cutting the fan leaves is so the bottom shoots can get more light, thus not affecting the growth of other desired shoots. the fan leaves just absorb the light and produces no bud.

Bad hypothesis?????????

Top branches produce the meat of the crop. The lower popcorn buds are barely worth trimming for hash. Leaves the leaves.

Dnt cut the leaves ever! If ya have to hack on the plant. Cut off the lower branches.
