Some of those shots made it look like you can easily go another 3-5 weeks. The larger girl could go another 2-3 weeks and be cut down if you're starting to get impatient, however, your patience will be rewarded in the end if you sit tight and allow them to run their course! =)
Consider giving them a PK spike right now, along with some Carbos if you aren't already (Molasses, SWEET, Bud Candy, FloraNector, ...) and really try to plump those girls up and give them what they need to finish. Some Cal-Mag will be good, too. You obviously want a bit of everything in the nutrient array in your soil, but right now is an important part to focus on a few specific flower nutes and really concentrate them.
Because you are in pots rather than being planted directly in the ground, it will be very easy for you to achieve a flush so that you can get some of those harsh, unused nutrient stores out of the soil, forcing the plant to start feeding on it's nutrient & carbo stores in it's fan leaves. When 90% of your fan leaves have gone yellow, or "autumed off", that will be a clear sign that you have some very smoothe smoke awaiting to be harvested.
Just make sure, if you goto the effort to properly flush for flavor, goto the effort to properly hang your plants and let them dry out properly. Don't try to speed the drying process up, and be careful of high humidity to avoid mold & disease. If you dry too quick, you steal flavor from the plant. After it's been properly air dried, get those jars out and do yourself a favor by jar curing for atleast 2 weeks.
Hope this helps!
