Day 72 of flowering? What kind of lighting are you using?

It looks to be flowering no more than 4 weeks. White hairs are most present and there are no buds (yet). That plant has a ways to go yet as there are no formed buds yet.

You either have lack of light or it's been flowering for a much shorter time than that.

EDIT: I just read your post again and I misread. Those are from day 36 then of flowering? We have no idea what they'd look like at day 72. Post a current picture so we can help answer your question a little accuratly.
