I'd say, trim away! I do it weekly or biweekly, and have never had
any adverse affects. I don't trim everything at once, that way there's
always plants still growing full strength while the trimmed ones get
back on their feet. A lot of the times, the trimming promotes new,
faster growth. It's sad to have to cut out plants, but it's very
necessary or the lights get blocked out, causing even slower
growth. Good luck and tell 'em it's for their own good!
