I think it may be time for a little update on this one. I trimmed the moss and it didn't look good anymore, so I removed it. I was also worried about over-watering the plant accidently (since the moss would dry out and turn white way before the growing media needed more water). I did superthrive it back around mid-june, and it seemed to make it grow faster, but as you can see, its not exactly looking much healthier.

Let me know what you guys think, because I honestly can't decide if its getting better or worse.

As you can see, the leaves are still really sickly-yellow, and I wouldn't be surprised if this symptom makes for an obvious diagnosis that I dont know.

Thank you so much,
