Likely causes
Fungal Leaf Spot
PossibleHow to tell: You will see dark, irregular patches that may have a yellow halo around them. These spots often appear after periods of high humidity or overhead watering.
What to do: Remove the affected leaves immediately to stop the spread. Improve air circulation around the plant and avoid getting water on the leaves when you irrigate.
Scale Insects
PossibleHow to tell: Look for small, brown, bump like structures on the undersides of leaves or along the stems. These insects suck sap and leave behind sticky residue or small discolored spots.
What to do: Wipe the insects off with a cotton swab dipped in rubbing alcohol. For larger infestations, apply neem oil once every 7 days until the pests are gone.

When to worry
Worry if the spots are spreading rapidly to new growth or if the leaves are dropping. A few isolated spots on older leaves are usually not a cause for alarm.
Stopping it coming back
Keep the foliage dry and ensure your plant is in a spot with good natural airflow.
