spots on oncidium leaf

I have bought this oncidium in the winter and has dropped its flowers. When I bought it, it already had these spots at the back of its leaves. The new growth light green and dark green streaks. What could this be. First foto: upper leaf. Second foto: bottom of the leaf.

I forget what it is exactly.
But oncidium and related plants are usually affected.
It's not going to affect the health of the plant any and doesn't really spread to other plants.
If you just don't like how it looks I find I get less spotting with higher air movement.
Some hybrids are more prone than others.
For instance, all my oncidium and zygo came with those spots. But now all of them are spot free.
With the exception of one zygo hybrid, and my sharry baby oncidium.
Those two, I don't think I'll ever see without spots.

Thanks. I was just a bit scared that it would affect all my other plants so I cept it far away from my others. It is also very special for me it has beautiful orange blooms that can have spikes up to a meter high.
