Can I use that until I can budget in some Orchid food?

If you want to use bulk-bought fertilizer, try to get one that has
been made for Rhododendrons or other low ph loving plants, and use it
at a quarter strength or thereabouts. Regular fertilizers may contain
ingredients (Lime? The stuff you put on lawns once a year, anyway)
that interfere with the acidity of your media.

I have been using Rhododendron fertilizer the last four months or so
without noticing any ill effects at a third of the price of orchid
fertilizer. Caveat emptor, though.

Some orcids prefer higher Ph values. I don't know if any of yours do.
