Say fella, What I see is a very healthy plant with buds that should double or even triple in size in the coming weeks with proper neuts. and lights. Its been my experience there should be significant leaf yellowing and almost all brown hairs. Like Tat says at 70% brown I would stop the feeding and go to just phed water maybe a little blackstrap. Keep giving the same amount at the same times you have been, get the humidity to about 40-45%,then at the first sign of yellowing in the sugar leafs start chopping. This method works well for me trim,dry,cure and in 8 or 10 weeks twist one up and knock myself stupid. Good luck my friend,be patient, and don't forget All plants are exactly the same only different.
