no, only trim, if your leaf's are dying,

actually what i do, rather than plucking off fan leaf's. i tie them back, unless they are totally dead, brown, crunch curly, or take 2 of the bigger leafs and twist them together out of the way. this is all you need to do.
you could trim, but i wouldnt. if you do trim. do it 2 weeks before you start the flower cycle.
there are more pics in my photo albums.
Enjoy!
