Worried about my new Paph.

[JKeys]

My new paph PEOY, which I purchased pnline from Piping Rock Orchids, had very bright green, almost yellowish leaves when i came in the mail. Assuming this was from lots of light, I moved it to a lower light area and the leaf color seems to have returned to a light green color. However, today while watering I noticed some dents in the leaves - small little dents scatter on a few of the leaves. I also noticed some white dust - like stuff, which I just assumed was dust that collected on the leaves. But could these be pests or a disease?
