Hey Tip, yeah i think you put them on 12/12 too early, you should put them on 12/12 when they're roughly half the height you want them to finish. So it really depends on what size closet they're in, but you should try to get them to at least around 12" before going 12/12. Personally i'd clone sooner rather than later, i clone when in veg, you can clone when they're flowering but you'll probably find it harder. How they doing now? Post some more pics, like to see how they're changin. If you wanna check my grow its at http://boards.cannabis.com/showthread.php?t=83381
Good luck
