Most likely
How to tell: You will see small green or black insects clustered on the stems and buds. They often leave behind a sticky residue called honeydew.

Environmental Stress
Possible
How to tell: Plants that are not getting enough sun or are stressed by poor airflow are more prone to pest attacks. The plant may look weak or stunted.
What to do: Move your plant to a spot with full, direct sun. Ensure there is enough space between plants to allow for good air circulation.
