Yellowing/rusty spots on my oncidium new shoots

[dipoledipole]

Hi everyone, my oncidium sharry baby 'velvet maroon' is developing two new shoots, but I started to notice these yellowing/ rusty spots on the new leaves. I have rubbed hydrogen peroxide and tea tree oil on the spots (I got crazily creative :0 ), now the yellowing/rotten spots seem to stopped spreading, but the rest of the leaves are still getting tons of these small white spots..is this orchid infected with a virus? what can I do now? Thank you very much!

yellowed areas - Looks like maybe some water got trapped in the new growth (maybe during cooler temps ?), and the leaves may have rotted a bit in those areas - do they feel soft or sunken?

the barely visible white dots - I can't see them, sorry ... Hopefully someone else has an idea

Hi Sonya, thank you for your response! And Thanks for pointing out the cold temperature, as I realized I have placed the oncidium near freezing windows (and humid, due to the condensations on the glass). As we received our first major snow storm yesterday, The spots got worse over night, now it's soft and sunken

Here's a picture:

It happens - it's possible the new growth may still be ok, outside of the damaged areas, but if not, the plant will put out new growth.
