I run Ex cheese. I have found that it has 3 dominate pheno's. It appears you may have the sativa nominate one I call # 2.....It will all run out about the same time....and I would say that your girls should stay together with maybe 2-4 days of differing maturity. That should work out good for you, so your trimming isn't slapped on ya all in one day....
Next time you take pics. Turn off the HPS lighting(or wait until they go out and turn on the normal room light - won't hurt the plants flowering) and take the pics then.
You and them will be fine....Don't sweat it.......
