How much longer till harvest??

I am in my 6th week of flowering with this bag seed plant I grew... Do these look about ready to harvest...?? Pics attached and thank you for your help...

You still got at 5-6 weeks I would guess, definitely over a month. Way too many white pistils still. I have about 95%+ of brown pistils, and when looking with a microscope I can tell that its not ready yet. I recommend getting a jewelers loupe, a microscope, or zoom in really well with your phone to check the trichomes.

At this stage it is hard to pinpoint a finnish date.
For sure 3 weeks. Not sure if 6 though... I would be surprised if it flowered 12 weeks (definitely possible)
Usually it will finnish 8-10 weeks from the start of flower.

Looks like it has at least a month to go. Good luck.
