Hey!
The two big girls look pretty good and could easily be put into 12/12 in a week.
Before switching to 12/12 I also recommend doing a bit of defoliation taking out the first nod and the first nod on the second nod.
I know that might sound weird but it pays out, because light won't penetrate to the bottom and the buds won't be worth it.. that way you using up that energy somewhere else.
As for the other two smaller girls, my point of view is they're not ready. you'll have quite a small yield because they aren't developed.
If you can grow those in veg for a bit longer, if you've got no choice because they're all under the same light then just root for the best.
What lights are you using?
What size is your grow space?
Using any nutrients?
