From the pic`s I`d say she needs 1 to 4 more weeks depending on what kind`a light you get on her.
What light cycle are you using ? Try to chuck 2 more red cfl`s on here and get them close, get as much ph`d bloom feed in her as she can take for one more week with the extra light
Bring the lights down to around 8 to 10 hours per day max and off the rest of the day let her get nice long dark spells
Flush for a week maybe 2 if your not using organic nutes if not I just water once with ph`d water and wait 3 days then turn the lights off for 3 days and cut.
Best way to dry is hang the whole plant and wait anything from 2 days to 2 weeks then cure for 2 week to a month but if you dry weed well you can sneak a few tasters in even after day 2 of curing I mean you have to open the jar to air it anyway right ? lol
She look`s like she could fatten up a fair bit, I had to go away on my 1st grow and left someone else to flush and cut it and they`d been running a long time but come down 2 weeks early, they were just small plants but that grow I got 1/2 oz of good top cola`s weed per plant when I could have had closer to an oz if I`d have been home to judge it.
Low power cfl and led set up`s can take 1 to 2 weeks extra to finish.
