Underwatering
Most likelyHow to tell: The stems will look limp and the leaves will feel dry or brittle. The soil will be pulled away from the edges of the pot or feel dusty.

Heat Stress
PossibleHow to tell: The plant droops during the hottest part of the day but perks up at night. This happens when the temperature exceeds what the plant prefers.
