Right, don't know why 33 was stuck in my head
 I'd second the call for another 2 bulbs in T5.I had a full T5 setup on my 110 (8 bulb) and ended up swapping out 4 of the bulbs for 2 175 watt MH's. For me, I got decent results with both. I just preferred MH for the shimmer. Plus my tank was in the basement so I had no worries about heat. Not sure what to tell you about why your corals aren't growing. Your light setup seems ok. Individual reflectors, close to the water... that all seems fine. Two bulbs will give you extra spread from front to back but won't necessarily add more light to corals in the middle for example. If the lamp is functioning correctly then I would guess the problem lies elsewhere.

Before you change to MH consider some decent T5 bulbs. KZ or ATI or Geisemann. Wave points are a lower end bulb and you and your corals would see a difference.

Also keep in mind that on a four bulb fixture with two actinics, you only have two bulbs doing the work. The actinics do nothing for coral growth. Like Kevin said, go with the higher quality bulbs. You could also use a higher spectrum bulb instead of actinics for the blue look, that way you make use of all four bulbs and more light for the corals.

yes, by all means, you need MH, T5s are for kids silly rabbit
 now in all honesty while I like MH, and as was mentions LEDs, I can't say run out and change tomorrow, nor can I say give it more time. what are you water peramiters? Ca, Alk, Mg, Ph, Temp. how much water flow do you have. befor spending a tone of money for MH I would make sure that you corect any other issues first. Steve

If I was in your boat I'd wait for a good mass-produced LED fixture to be released as previously mentioned.
I don't think your issues are inherently a T5 problem. It's an issue of a suboptimal T5 fixture with suboptimal bulbs and suboptimal number of bulbs problem. You just don't have a very good T5 setup all around. With that in mind, I would certainly suggest a change given your aquarium dimensions and desire to keep SPS. I would just be inclined to make the change to LEDs as opposed to MH.
