Check these first

  1. Check if the spots are white and powdery.
  2. Ensure the plant has enough space for air to circulate.
  3. Look at the underside of the leaves for signs of fungus.

Likely causes

  1. Powdery Mildew

    Most likely

    How to tell: A white or gray powdery substance appears on the leaf surfaces.

    What to do: Improve airflow around the plant by thinning out crowded foliage. Remove heavily infected leaves and treat the rest with a mixture of water and a little baking soda.

  2. Leaf Spot Disease

    Possible

    How to tell: Dark or brown spots appear on the leaves, often with a yellow halo.

    What to do: Avoid overhead watering to keep the leaves dry. Remove and dispose of any infected leaves to stop the spread.

When to worry

If the spots cover most of the foliage, the plant will struggle to photosynthesize. Small, isolated spots are usually easy to manage with better care.

Stopping it coming back

Water at the base of the plant to keep leaves dry and ensure the plant is not overcrowded.
