dieffenbachia leaf with spots

In this photo, you can see the gray spots that are appearing on several of the dieffenbachia leaves. This leaf in particular is wilted and may indicate that the plant is under water-stress. Exposing dieffenbachia leaves to direct sunlight can cause issues like gray spots. Under watering a dieffenbachia can cause wilting and make the plant more susceptible to light stress issues. See water requirements for dieffenbachia.
