Coffee for Fertilizer?

[Kevinator]

After meeting with a professor at UC Irvine I have now officially jumped onto the carnivorous plant train and I can't get off. When doing research on growing Nepenthes pitcher plants, I read multiple reports that coffee worked miracles for these plants, whether for the terrestrial or epiphytic species (and from what I heard, many of the highland species seem to require similar conditions to Masdevallias). Since I'm too lazy to order MSU fertilizer online, I was thinking if I could use RO water coffee with my orchids. Any of you guys have experience with this?
