Likely causes
Mealybugs
Most likelyHow to tell: You see white, fuzzy, cottony masses in the leaf axils or along the stem.
What to do: Dip a cotton swab in rubbing alcohol and touch it directly to the bugs to kill them on contact. Repeat this every few days until you no longer see any signs of them.
Spider Mites
PossibleHow to tell: The leaves look dusty or stippled with tiny yellow dots, and you might see fine webbing between the leaves.
What to do: Wipe the leaves down with a damp cloth to remove the webbing and mites. Increase humidity slightly or use a gentle insecticidal soap spray.
