Interesting. As it could also be water parameters, dosing supplements (or not), temp swings...etc.etc. and not just a lighting issue.
The few SPS I have (easy care for types) are growing well under my LEDs. Don't ask me the names of them... I have no idea (I'm SPS Dumb). I've HEARD, some are tough to care for... but, fity2pounder‎ is using LEDs over his tank (and he's got more SPS than I, as well as harder-to-keep types). Best to ask him how his growth is doing, as he's using THE SAME LEDs I'm using (custom coloration).
