Yes, for flowering you will want a red spectrum light. At least wait on the 12/12 until you get some reds in there. I would flower when they are a little bit bigger, Since you are still in veg you can LST or maybe even SCROG if you are dealing with height issues. Your plant isn't a seedling anymore =] I wouldn't give it any nutes for awhile though, at least maybe till you are flowering. Keep us updated :jointsmile:
