You're right Kirk!
I have a worm compost at home, so I fertilize with worm tea every other watering for all of my orchids, not just the paph. I have a 10-10-10 fertilizer at home that I am considering using every other time I fertilize. I'm not sure yet...still learning about that kind of thing. I am nervous about causing damage with a harsh fertilizer.
I keep the paph on my dining room table...there are two large French doors that are southeast facing in the room where the paph stays. It does not get any direct light though, as it is slightly tucked away in the "dining nook area". I am not sure if that is helpful...my phals have been happy in a similar light situation.
