Whyyyyyyy????

bump

Usually a sign of water stress.

Curling upward/inward it’s possibly trying to hold onto water stored in its leaves, so might be from under watering. Do you flush the full plant or water with a cup/can?

It might need a flush in the bath or shower if the latter.

Sometimes only the top 2/3 of the soil might get wet with cup watering leaving the roots at the bottom waterless.

Curling can be from overwatering too but tends to curl and droop where this doesn’t look as if it’s drooping.
