masdie culture

I am looking for info on the culture of masedvallia species. I have my first one currently, masdie vietchiana(sp?), which is in bloom and has another spike on the way. question is, what do you fertilize with and how often? I gave it a little diluted 20-20-20 last week and it seemed fine, but now the bloom is fading and im not sure if its the salts in the fertilizer overpowering the plant, or if the plant is just done with that flower. I bought this plant in bloom so I cant say how long the first bloom was on the plant. I have it in the brightest section of my phalaenopsis growing area over a fog maker to keep the humidity up and the temp down as much as possible. Any suggestions?
