Since you know the days since you started to flower you probably know when a white widow is supposed to be ready. I thought they were like 9 week plants. So if that is true you have 3 weeks left. I also notice a good percentage of fresh new pistels and not a lot of dead hairs so I would say they are still growing.
I would start flushing if I were you to get rid of any nuts still in the soil.
Good luck
