White spots on dieffenbachia plant
Does anyone know what are these white spots on my dieffenbachia plant (please see attached images)? I spray the leaves with water every day but these do not look like water spots. They are not sticky but chalky so I wonder if they are mealybugs. I sprayed the leaves with soapy water once but it did not seem to help.
I don't see any bugs on the plant. These spots mostly appear around the edges on the front of the leaves. I also saw a few thin white streaks on a stem. The plant otherwise looks healthy. I have only had it for the last 3 weeks.
Should I be worried about this?
