This house plant of mine has developed some black spots on about a handful of leaves. It is a very large plant, some vines are about 4-5 feet long and seems to be very healthy. When leaves do die, they turn yellow n fall off . I have never noticed black spots like this. Does anyone know what these spots are? Should I be worried? I have several plants located in the same area as this one and this is the only plant with the spots.
