I've grown Psychopsis before, they don't generally do well in full Sphagnum moss as a potting medium. I'd use medium grade bark instead.
They like to dry out between waterings, but not by days. Let it dry out, but as soon as it dries, water again. I also don't like to grow them very wet, because I've found that they can rot quite easily as well.
I also would not be so ready to divide Psychopsis. They are somewhat slower growing than their Oncidium cousins.
These like it intermediate to warm.
Bright indirect light.
Hope you can save your Psychopsis.
