I would give her a dose of nitrogen and clear all that yellow up keep her going a few more weeks I would say about 2 or 3 and you will end up with a bud thats more dense and had more trichohme delevopment and better maturity usually most growers wait until 90% of the hairs are orange and then curling backwards that is a sign they are mature enough for harvest. Nice looking plant though bro you do what you want it is yours after all :)
