Keep or Throw; Virus or Pest Damage?

[theglassdesert]

Hi, I’m a new member here and this is my first post!
I recently got into the orchid growing hobby, specifically polychilos Phals.

One of my plants seems to have some chlorosis and pitting on the leaves but I can’t tell if it’s pest damage or a virus. I’d hate to throw it because I don’t have that many in my collection but should I? I can’t afford to buy virus test strips sadly . Can somebody with more experience with orchid problems help? Thank you

Plant: Phal. LD Sun Rose ‘Freys’ from HappyPlantUSA, supplier is MIKI orchid in Taiwan.
