12/12 will finish your plants and ripen your bud. You dont need to switch back to anything higher than that unless you want the plants to STOP making bud and start growing branches and leaves again.

Only switch to 12/12 when you are ready to flower. By switching the schedule back and forth you will stress out your plants and possibly turn your ladies into hermies.
