Looking nice and healthy, are you planning on flowing under the fluorescents too? You can definitely do that, but I would recommend either getting a 250 watt hps, tho that will be hotter, or 2 100s or a 200 watt cfl with like a 2700k spectrum. Those will be a bit more intense and get better light penetration for your plants give you more and thicker buds thought out your whole plant.
Either way you don't have to worry too much till you switch to 12/12, tho lights are plenty for vegging. When do you plan to switch over to flowering?
