The lower leaf is the oldest, aswell... the one with the necrosis... Now I have 10 psuedobulbs, three of which have leaves... As for the mites, I couldn't see a thing. It seems smooth.

Ross, having excluded mites sucking the sap out of the cells of your leaf and leaving pinpoint necrotic spots, I have no further suggestion except to say that I do not think that it is a virus. If the leaf turned brown and mushy it may be a bacterial rot so it may be good idea to dip your plant into something like Physan which I think is a quatnerary ammonium compound but would not bet on that. Also check your root system. Good luck
