clones look healthy but you should ditch the fixtures and go buy some clamp lights or sockets so you can hang the bulbs directly above and add more of them, and also be able to lower and raise the lights to achive maximium growth by keeping them with in inches of the plant otherwise you'll get lankyness between nodes, IMO you should use 18/6 for vegging sometime 24 is a little too much. Also what kind of soil are you using? ANd what kind of nutes will you be using?
