Hi PinkeyGreen.
Welcome to the site and community of members that gathers here.
I look forward to others thoughts on this, but the whole "stopping nutes/flushing" topic is kind of a personal preference/practice thing. Some growers swear you must, some think it's a wasted opportunity to encourage the plants final phase of growth and robs them of their full potential. Even the growers that swear you must will often concede that it's less important at the least and often unnecessary if growing with organic nutrients.
It appears you may growing in topsoil with sphagnum rings covering your pots - correct? Can you give us a clue as to whether your using organic or chemical nutrients?
I think it would also be helpful to those wishing to offer suggestions to learn what kind of buzz your looking for from your girls as many on the site will use magnification of trichomes to evaluate their color and judge harvest time. For a more cerebral "head high" with some uplifting qualities growers will suggest harvesting with more cloudy/milky trichome color, and for a more "stoned/couch lock" buzz wait for more amber colored trichomes.
From my very limited experience, the last couple of weeks seemed to drag on forever. I would think I was a week to 10 days out and 5 or 6 days later I would still think I was at least a week to 10 days out.
Based on just the photos and having no idea what kind of high your looking for, I'd like to suggest you have at least 3 more weeks. I believe your buds will continue to swell and more of the pistils will turn red/brownish and shrivel a little.
Again, welcome to the community and happy growing!
