Oh, with regard to fertilizer, most orchids are not heavy feeders.
Cymbidiums, Catasetinae and Vandas are some that like more fertilizer, but feeding them once a month on average should be enough.
Many researchers feel fertilizer may help with producing a few more flowers per spike but fertilizers in general do not cause many orchids to bloom. If the orchid is not getting the proper water, the correct light, you can fertilize until the proverbial cows come home and they won't bloom!
