Leaf density, defoliation, nutes, genetics, just healthy?

Plants look great, I would suggest "lollipopping" the under storey but leaving as many healthy green leaves as possible up top, these will make the energy your plant requires to grow her biggest and best buds. Just remember - Maximum amount of healthy green leaves = maximum energy production = maximum growth! A lot of people defoliate excessively/unnecessarily without really understanding what they are doing, thinking less leaves means more energy for bud growth, but with less leaves, there will be less energy production, so there can be no "extra" energy going into bud growth! Personally, I only ever remove yellow leaves. Besides, if your plant would not NEED those leaves, it would not grow them in the first place! Hope this helps, Organoman.
