Masdevallia mendozae spotting

[Kevinator]

Hey guys. Does anyone know what this is caused by? I recently bought it and I don't remember it having this much spotting. I'm assuming it is from heat stress but the temperature in my terrarium stays at around 75 degrees f during the day and 68 at night. I have a fan on from 7 am to 11 pm so I'm not sure if it may be fungal.

I don't know but wanted to advise you to isolate it and find out. I lost one of these recently to anthracnose. Couldn't find the anti fungal needed to kill the disease before I lost the plant, it went really fast.
