Paph Acmodontum Crown Rot

[zackleib]

I recently got this P. Acmodontum and noticed it was planted with a thick layer of sphagnum at the soil surface. It was retaining too much water, for my growing conditions, so I removed it and replaced it with a bark and sphagnum mix. I did lose two leaves when I originally got the plant, and noticed some rot at the base of them. At the time, I was not super concerned, as the new fans seemed very healthy.

As I was inspecting the plant more closely this morning, I noticed some brown on the plant's crown. Being a concerned plant parent, I wanted to get some second opinions. The plant is very sturdy, and when tugged on, none of the leaves seem to budge. I am trying to water less frequently, to see if this may help as well. Any advice or opinions are greatly appreciated
