remember MOre light = Bigger Buds    Yes - take all the fan leaves off   here is a good rule : in defoliation the "sapce" defoliated has to be 2/x's it's size of the fan leaf defoliated. - this is for general defoliation NOT heavy  hope this info helps   (you are moving light blockes the sugar leaves take over !!!!! - have done ot both ways the latter works best)  here is how defolation goes :

do a heavy defo in week 4 of Veg

do a light  defo 1 day berfore transiton stage (12/12)

do a heavy defo in week 4 of flower

(very light pruning thr-out grow -- 3-4 leaves)  Its all about LIGHT and BUD SITES
