I say yes provided you are watching PO4 and NO3 levels closely.  Feeding corals has been disputed and discussed for many years and it was once though that corals derive much of their nutrition from photosynthesis.  In my observations, some coral species kept in a closed environment such as our aquariums benefit greatly from occasional feedings.  The color on this frogspawn has darkened and became richer after a short time with target feedings.
