you have to be careful what your taking pics of...the last picture looks to be just side branches forming and not a male sack or a pistil...the preflowers will only come from the spot in between the main stalk and a side branch then on an actual branch in between the main branch and any new 3rd branch off the branch, follow?? so some new growth you see will always be just branches growing but that will stop when flowering kicks in...you have been flowering three weeks now and noooo white hairs anywhere tho??
