Foxtails?

i'd let them ripen, but don't expect them to fill in. i trim this off after harvest.. save for bubble hash or extracts etc.. no need to throw it out. definitely ignore a tiny percent of yield when determining harvest point.

no

I never cut them. I would let her do.

I've done both. Left & cut. If your plant is out of pre flower the risk of stress that'll bring hernies won't happen Lots of ppl remove them, or lollipop with no ill affects. It looks really thin..I can't see your whole plant but either way Idc any major issues by doing it. Yet, it won't hurt neither. You could HST that top once there's still fattening left u can do this. Or move your light further away from. Its really up 2u mate. Good luck

Reduce temps and just harvest the whole plant when it is ready. Stressing it by cutting on it is probably not the best option.
