Likely causes
Powdery Mildew
Most likelyHow to tell: You will see a white, dusty fungal growth on the surface of the leaves. It often starts as small spots and spreads to cover the whole leaf.
What to do: Improve air circulation by thinning out surrounding plants. Apply a neem oil spray or a mixture of one tablespoon of baking soda in a gallon of water to the affected areas.
Leaf Spot Disease
PossibleHow to tell: Small brown or black spots appear on the leaves, sometimes with a yellow halo. These are caused by fungal spores splashing from the soil.
What to do: Remove and dispose of all infected leaves immediately. Water only at the base of the plant to keep the foliage dry.

When to worry
Small spots are manageable, but if the entire plant is covered in mildew, it will struggle to photosynthesize. Remove heavily infected stems to save the rest of the plant.
Stopping it coming back
Space your plants out to allow for good airflow and always water at the soil level.
