Help - epiphytic orchid - what to do?

[Roberta]

Welcome! You have received great advice! I agree totally on the fertilizer. The specifics of which one don't matter much, for pretty much any granular fertilizer, about 1/2 teaspoon per gallon works for me. A pump sprayer (1 or 2 gallon) would work well for that. Just mix up the solution and give the roots a good bath.

That Cymbidium below it could use some too. (And in the spring probably benefit from repotting unless it is been done in the last couple of years).
