Maybe not even two weeks. At this stage in flower, things can change really fast. You might be cutting them a week from now. But I'd say two weeks is a good guess, although I'm basing that off of only one of the pictures. How are the trichomes looking? Have they stopped sprouting white pistils?
Looks like you did really well for the first time out; looks like a lot of small things that could have easily gone wrong went right instead. It looks very much as though you didn't make the kind of mistakes most first-timers make - overdoing things. Looks like you kept it simple, and used common sense. Congratulations; wait until you see what happens when you apply what you learned on this one to the next grow. You should keep a grow journal on the next one.
And if you're taking a poll, mark me down in the "don't flush" column. Especially if you haven't been hammering them hard with PK, like I always do in bloom. And it's obvious from the leaf tips that you haven't. I always feed at least lightly right up to the last couple of days; the plant doesn't transport the nutes directly to the buds, so there is no mechanism for the buds to have chemicals in them.
Just make sure you apply the same patience and discipline to the cure as you did to the grow; unless you're incredibly lucky, it's obvious you did a lot of research to get your grow dialed in, and it's just as important to hit the books for the cure as it is for the grow itself.
