If you had to take a rough guess how long would you say those plants were in 12/12. I know you said you don't know but just take an estimate.

About 5-6 weeks or so?

If so I'd say judging by those trich pics and that most of the plants look sativa dominant, I would say another 4-6 weeks.

I'm in the same boat as you. Check out my flowering log link in my signature. I just started week 7 of flower and I'm still expecting to go about another 3-6 weeks. My plants are still all clear/barely cloudy like yours.
