Check these first
- Inspect the undersides of the leaves for white bumps.
- Check if the leaves are staying wet for too long after watering.
- Look for signs of overcrowding in your container.
Likely causes
White Rust
Most likelyHow to tell: You will see small, raised white pustules on the undersides of leaves. The top of the leaf might show yellow or pale patches.
What to do: Remove and destroy all infected leaves immediately to stop the spread. Improve air circulation around the plants and avoid splashing water onto the foliage when watering.
Fungal Leaf Spot
Most likelyHow to tell: These appear as dark, irregular brown or black spots that may have a yellow halo. They often develop when the air is too humid and stagnant.
What to do: Prune away the affected leaves to reduce the fungal load. Ensure your plants have enough space between them to allow for better airflow.

When to worry
If the spots are spreading rapidly across the entire plant, it is time to discard the affected stems. A few small spots on older leaves are common and usually not a major threat.
Stopping it coming back
Keep the foliage dry by watering at the base of the plant rather than overhead. Provide consistent airflow to keep the leaves from staying damp for extended periods.
