Im thinking of switching to 12/12 light cycle on t...

hey norb, switch away my friend ! you see how the plants have that light green growth, basically that's the preflower, and it means the plant itself is ready to blow; only question now is : are you ! just a couple of things, i see the leaves really dark green that means too much N , and i see the leaves being really puffy, that means overwatering. i would cut out the nutes with N in them for a week or so just so the plants can get that bloom ratio they'll prefer during flower. Second that cupping on the leaves of the blueberry muffin might indicate some sort of root issues, so you might want to stay on top of that with some enzymes or chelation agents. Hope this helps ! 🚀
