My question what happened here. Within 14 days you can see puddles and spots appear on the leaves. Masdevallia scabrilinguis dropped almost all the leaves. At my Masdevallia filaria you can see puddles and spots. At Lepanthes dodsonii, spots appear and then the leaves shrivel. All circumstances haven't changed, it just got cooler. I water at five o'clock. There is a lot of air movement. Almost all leaves move more or less. LF is 75% to 95%. Temperature 12.5°C to 19.5°C I know these plants all grow between 1500m and 2100m. That would be temperate temps. Can the cause be too cold and probably wet leaves? Or could there be other causes.
