Are you running carbon? If so, that seems to affect GSPs, frogspawn, Yumas & blue cloves, in my experience. If you run carbon and still would like to do so, use some "Essential Elements" from Kent Marine to bring back the necessary trace minerals. That worked really good for me. If you don't run carbon, not sure what exactly causes the problem you are experiencing - seems there are some minerals missing? I might be totally wrong...
