here is my honest opinion and i hope u dont take it personally. those plants are about as lanky and scroney as a plant can be. they need light...more light! put the lights u do have right on top, or in the middle of the plants. the way u got the light now is making the top of the plant strech for light and not growing "bush" or branches. my suggestion, take them out of 12/12 right now and start re-vegging them. looking at the stems on these plants, u will be lucky if they can support the very little bud they will produce without falling over...and thats a big IF. im not knocking ya dude, u just need to freshen up on some basic technical issues before some of the small problems now, become bigger later.
