Is my goniopora melting?

Today when I got home I noticed there was a brown/green slime covering half of my goniopora frag. I blew some of it away with a circulator and it appears that the polyps are still under it? It has looked perfectly healthy to this point with full polyp extension.

It is in a high light, high flow area. I broadcast feed coral frenzy 1x per week, 10% wc twice a week with io reef crystals.

Params:

1.025 sg
78*
Cal 440 ppm
Alk 10 dKH
pH 8.2
Ammonia: 0
Nitrite: 0
Nitrate: 20 <-- prime reason? But its been apparently surviving fine for months in this environment.
Phosphate: < .2 ppm

I know gonioporas are picky but poor parameters would cause a slow death no? It has been fine til today.

Should I target feed it, and more often? I know I gotta get my nitrates down.

All my other corals other than my favia are doing awesome.
 
Alright, I will feed it tomorrow. I heard mixed info on whether it was required to be target fed or if broadcast would be sufficient.
