How much height do you have to work with?
That doesn't give you alot of height for stretch.I personally would let them get around 16 inches then flower. They are looking good. Nice and bushy.
Good advice. Should I replace the 2700K with 6500K again then?
I'm not a cfl guy. Ask around I can't help you on that one. Don't go to flower then back to veg you don't have the height to let them get that tall.
I probably have another foot and a half of free space up, but not much in width and depth ... I have 6 plants, none have shown sex yet. Could I switch to 12/12 until they show sex and then go back to 24/7...? I am thinking a few could be male statistically...
these pictures are much more clear and detail the dimensions of the plant better.

yes, you can switch to flowering stage to determine sex and you can switch back, but it will slow your process by so much. you'll spend a month or so waiting for your plant to revert back to its vegetation stage before it does anything else.
i suggest leaving her under 18/6 or whatever you have her on now until it sexes (doesnt seem too far away).
that way you can take her into flowering and you'll save atleast a months time being wasted.
This I agree with. Maybe not lose a month but , a week or two wasted. Not worth it in my book. It sounds like you have around 4 feet. I'd grow them to 20 inches then flower. That should get them around 30 inches or so at the end. You could harvest an ounce or two per plant. Good luck!
