I don't know Rachel, I've never had a turbinaria do well here, in my particular lighting/stocking etc.
I've sold off two cups and now one scroll, because I don't like the polyp extension, and feel they can do better elsewhere.
In one tank, I had less light and a cup coral was doing well, until a coral beauty began keeping the polyps retracted, as sort of a game, from what I could tell.
