Answer 1

There are a few reasons why this could be happening. Unfortunately, both, underwatering and overwatering can cause this issue. A moisture meter can be used to know the water content of the soil, for sure. This can be mitigated with proper drainage in the container. Make sure that moisture can leave, freely.

Nutrients could be lacking. This can be detected with a meter, as well. It may be necessary to feed with an all-purpose fertilizer.

Pests, and disease from pests can cause issues as well.
