sorry for the out of focus pics my camera doesn't do well with close ups.

What other things could be causing the dry and crispy edges of the begonias. My lace leaf begonia was growing great then all of a sudden the leaves are drying up and falling off. And it is in a terrarium.

When I spray the plants I blast the tops and bottoms of each leaf. My poor little escargot only has three leaves left and two of them are looking bad.

I took more pics, but they are still fuzzy. Around the edges of the leaf you can see the crispy dry edges. It looks blue in the pic, but it is actually brown.

Thanks so much for your help
