WHY DOES THIS HAPPEN

An airborne fungus known as Cercospora beticola can cause small brown spots to appear all over plant leaves. This most commonly occurs on sugar beets and leafy vegetables, however, it can occasionally affect houseplants too.

Like with other fungal infections, Cercospora beticola can take hold if your plant has been left overly wet for a prolonged period of time, for instance, if you accidentally left your plant standing in water for too long or if you overwatered it.

Overwatering is, in general, very bad for plant health, so it's important to try and make sure you only give your plant as much water as it needs in order to keep it happy and disease-free.
