These grey spots appeared on the leaves of my philodendron overnight. They don’t wipe off so I don’t think it’s mildew. Anyone know what the problem is?

Maybe it is natural some philodendron naturally produce a sugary sap that can leave white spots behind.But just try use distilled water if hard water is an issue in the area.
