Nice plants you have going there. Try moving your light down a bit because your plants are still small so they'll need as much as light as they can get specialy because your using fluorescents and not "proper" lighting so they'll need to be a bit closer as your not getting as many lumens, good bulbs to use are Cool white and warm white bulbs (BTW).

Aswel Miracle Grow, I suggest cutting the plants from that alot of growers have had bad experience and bad tastes with miracle grow, your choice but I wouldn't use it.
