I have several violets that are developing very tight brittle leaves 2 are variegated foliage and this trailer "Kentucky Shine". I don't see any evidence of mites but even by reducing light exposure I am not able to loosen the leaves on any of the 3 that are doing this. Others under same condition growing well.

I guess I should destroy them and go on, but I would like to make this a learning experience, at least.

HELP, PLEASE!!
