Nothing to worry about. It’s most likely damage from watering with cold water, too close to lights out, or watering heavily when the plant was really dry. Make sure you are watering with room temp water and preferably well before sundown or lights out. If a plant gets really dry between watering then water a little at a time to slowly rehydrate.

A picture of the whole plant would help.
