T5 lighting enough for a 90g

I do want to keep both SPS and LPS, I hadn't realized that MH may be too much for the LPS even low in the tank. I have a couple of SPS frags I got about a month ago under T5 lights (about 13" under light source) and my digi has already sread to the rock I glued it to with lots of new growth. My milli started to lose its polyps at first but has since revived and has started to grow out as well.
