Check these first

- Ensure the plant has enough space from other plants.
Likely causes
Powdery Mildew
Most likelyHow to tell: A white, powdery substance appears on the surface of the leaves.
What to do: Improve air circulation by thinning out nearby plants. You can apply a neem oil spray or a mixture of water and baking soda to the affected leaves.
Fungal Leaf Spot
PossibleHow to tell: Dark brown or black spots appear on the foliage, often with a yellow halo.
What to do: Remove and dispose of any heavily infected leaves to stop the spread. Avoid overhead watering to keep the foliage dry.
When to worry
Small spots are manageable, but if the entire plant is covered in fungus, it may lose its leaves early. It is normal for foliage to look a bit tired as the plant prepares for summer dormancy.
Stopping it coming back
Water at the base of the plant rather than over the leaves and ensure good airflow.
