I've just purchased a lipstick plant which appeared very healthy. After sitting in a medium sun window for a few days, it appears to have contracted some form of leaf disease...there are clusters of little bumps that look like pimples surfacing on some of the leaves, and looks like its spreading!! Any idea what it might be or what I should do?

welllll...i've read about aphids, and from the description, i don't think that's what they are...thanks though....
