ahhhhh!!!! i know someone.... who got this same horrible advice and took it and has been using it off and on for the first 1 1/2 weeks of flower! just trimming back fan leaves for lower budding sites... but the situation is that it has not seemed to hurt the plants at all. there is still lots of foliage left on the plants. it just seemed to make sense because they seemed to get over grown otherwise!!
the buds also seem to be growing fat and dense.. just potentially a little slower than typical? not sure as this is this certain 'someones' first grow.. haha. now im just pissy for listening. but like i said before... there hasnt been any negative effects that you can see so far!
