DISCLAIMER::: NOOB ADVICE- DISREGARD BELOW -
What kind of light are you using? You may want to think about cranking up the intensity by dropping it a few inches above your plants, they look solid enough to be able to take it. looks like they're just begging to grow

also If you don't already do this: cover that big gaping hole in your top, light will get in your res and mess everything up. Also you may want to put some duct tape or something to block the light from your air-tube holes. you may even want to consider drilling those holes on the side instead. If algae starts growing your plants growth will stunt.
