Likely causes
Aphid infestation
Most likelyHow to tell: You will see clusters of tiny green or black insects on the undersides of leaves or near flower buds. They often leave behind a sticky residue called honeydew.
What to do: Spray the plant with a strong stream of water to knock them off. If they persist, use a mild insecticidal soap or neem oil spray every 5 to 7 days.
White blister rust
PossibleHow to tell: You will notice small white or yellowish pustules on the undersides of the leaves. This is a fungal issue that can weaken the plant over time.
What to do: Remove and destroy any infected leaves immediately to stop the spread. Improve air circulation around the plant and avoid getting water on the foliage when you irrigate.

When to worry
A few aphids are usually manageable, but a heavy infestation can stunt growth. If the plant is covered in white pustules, it is likely too far gone and should be removed.
Stopping it coming back
Keep your plant healthy with plenty of sun and avoid overcrowding. Check your plants weekly for early signs of trouble.
