Looks pretty good

I see a lot of fat, happy pseudobulbs so it looks nice and hydrated. The roots on these turn brown, so they look very different than the roots on something like a phal. Don’t cut them off, they could be very much alive. I wouldn’t worry about the rust spots unless they start spreading. Could have been a little infection from getting cold and wet leaves. Same for the black lesion, but is it soft at all?
