Milty Malady

There are several areas where the damage looks like a mirror image on both sides of the leaf. I am suspecting physical damage rather than a pest...... Maybe a bent leaf, pinching or accidental gouging with a stake or a name tag while the growth was small?

Thanks for your feedback and observations. I had an oncidium with the exact same markings about six months ago, so I'm thinking it would have to be a coincidence if the culprit was due to a physical insult. The two of them are in proximity to many other orchids, but not to each other, and none of the others have had this issue. I'm not sure if the pictures are clear enough. It's almost as if these spots are like plaques of some sort where there is a clustering of the leaf's flesh to one spot (but clearly not scales). My fear is that this could be a virus but again, none of my other miltonias or oncidium nearby have it...So that leaves me with nutritional, but still weird!
