Looks like a severe mite infestation.

Get a good miticide and closely follow the directions.

By the way, the genus is dendrobium

Rubbing alcohol (isopropyl) 70% will kill the adults quickly. You must spray all surfaces of the leaves, the whole plant, the top of the medium and the pot. Do this as soon as you see evidence of mites.
