I think that should be enough. If you think about it, I have about the same as you since my other 2 tubes are just actinic. I think the aquablue special is 12k if I remember well and that's what I have with a fiji purple.
My guess is that something else is going on in your tank, maybe too high temperature? Gorgonians usualy don't like too hot temperature. Do you have a refractometer to mesure your salinity or do you use a plastic tingy hydrometer? Do you have an automatic top off or do you top off manualy once in a while?
