Ive only been growing a little over 2 years but most my flower expirience came recently. The others you tagged are waay above me in knowledge but I think you can chop now or in next week.
Though if the white hairs and nanners keep coming it could be throwing things off and can keep going forever, happened to me once but with autos. From stress like nanners, foxtailing etc.
I usually get a 100% orange hairs pretty easily with photoperiods if I just let it go another week or two. I suppose it can happen with photos too. As I check again youre like riiight there almost done.
BTW my beloved strain I almost thought ended a bean hunt through nanners and grew lots of seeds, nanners CAN pollinate a whole room. Just a fyi be careful with other plants or residual pollen.
