The lighter green bands on the leaves could very well be the beginning stages of sun burn. Just keep an eye on it.

To me the flowers look like this is a Miltonia. Possibly pure Miltonia, or it may have some Oncidium in the background.

You are right, it is a sunset miltonia. I have identified it after posting this thread.
I have found tiny black dots around the area where the leaves start at the tips of the pseudobulbs. They also go inside the leaves, so now I'm wondering if this could be a fungal infection. Besides those tiny black dots there are bigger but brown patches that aren't really circular, these two could be unrelated but I thought I'd mention it... Should I invest in some hydrogen peroxide 3% and spray the leaves in case it's fungi?
