Q.leaves
Leaves drooping and curling in but still blooming on my crown of thorns. Why? They’re outside.

During active growth the entire root ball should be watered but allow the top inch to dry between waterings. After flowering allow the top third of the soil to dry between watering. If the soil dries out the plant will drop it's leaves prematurely. Crown of Thorns can be finicky and react to stresses.
Here is a link to refresh you on the care requirements.
