Check these first

  1. Look for white dust on the leaves.
  2. Check if the plant is crowded by other foliage.
  3. Feel the humidity level in the room.

Likely causes

  1. Powdery mildew

    Most likely

    How to tell: White, powdery fungal patches appear on the leaves during humid weather.

    What to do: Improve airflow around the plant by moving it to a more open area. You can wipe leaves with a damp cloth or use a mild neem oil spray.

  2. Water splashing

    Possible

    How to tell: Small brown or tan spots appear where water droplets sat on the leaves.

    What to do: Water the soil directly at the base of the plant rather than pouring water over the foliage. This keeps the leaves dry and prevents fungal growth.

Stopping it coming back

Keep the leaves dry when watering and ensure there is plenty of space for air to circulate around the plant.
