Hoya plant....leaves becoming thin

Nancy Chavis
by Nancy Chavis
the leaves on my large Heart Leaf Hoya were plump and healthy for years . Now, as of a few months they are becoming thin....the vines in the leaves now are protruding. The color is still good. So far the leaves are not dying. I've checked carefully for bugs and haven't found any, I would hate to lose this large beautiful plant. Nancy
