Dendrophylax lindenii - Ghost orchid fertilizing?

[farley101]

I recently picked up a very smol ghost orchid that I am getting used to taking care of. It is mounted on cork, and I have it in my little warm, humid, and bright grow space but it hasn't really done much. I try to water it at least 2x a day, more if I can, but it always seems dry. Just some tiny green spots on the end of the root tips give me an idea it's alive still at least!

I decided to drape a bit of Spanish moss over it to keep the moisture around a little bit longer, I just started today so we'll see how that works.

So after all that exposition, I generally add very dilute fertilizer to all the rest of my plants each watering and wondering how to handle the ghost.

Since I water it a lot more often I know it won't need the fert solution as much. But once a week or once a day or something in between? I usually have a 40-50 ppm N mixture since I only water most plants once a week or less. Any thoughts would be appreciated!
