Do you think this is the normal drying effect of an old leaf? Are the centers brown?

It could be low humidity or too much light. Or it could be that the stems are too long and the crown needs to be rerooted. Years ago it was genrally regarded that episcias make their best foliage in low light--such as lighting for an AV. But, they flower best in higher light. I can't say that I completely agree with this but I think it points to cultural factors rather than something else.
