Dying masdevallia measuresiana!

[AJW]

Hold stop and re think.
Masd's are relatively cool growing and like both moisture and plenty of air movement with around 30 -40% shade. The spotted leaves I have found come and go be it frustrating the look. I have found a very mild fungicide or general purpose plant oil tends to spruce them up. What medium are you using I tend to use a very fine bark. Once you have re-potted apply with watering a weak solution of epsom salts (for two waterings) then stand back it should take off again. Good luck. This is a nice genera species when in flower.
