Without photos, it's hard to know exactly what's happening to your plants, but I have a couple of guesses. White, fuzzy spots could be a description of a mealybug infestation (Google mealybugs to see some pictures.) It could also be a fungus growing on the surface of the leaves, probably in places that were wet for a while. In either case, a good first step would be to wipe the fuzzy spots off using a mix of water, a little dish soap, and a little isopropyl alcohol, then wait to see if the problem returns.
