Terrarium Plant Question

Terrarium Plant Question

Fellow plant folk: Here is a photo of a relatively new leaf on my new butterfly stripe plant (Cristia obcordata). It has lived in my terrarium for a month, but I seem to be getting leaves with yellowish pock marks on them. I've cut a couple leaves with this already, but now it seems to show on the new leaves. I assume this a fungus, but have never had to treat one indoors, especially in a terrarium. If so, any suggestions as to what might be done? Sulfur? I'm airing out the terrarium to reduce temperature and humidity, but that seems a temporary measure. Any advice is greatly appreciated. ~W
