Why is my cart not hitting but has airflow?

I'm encountering an issue with my cart that's leaving me puzzled. Despite the fact that there's clear airflow present, it's not hitting as expected. Could you help me understand why this might be happening? Are there any common reasons for a cart to have airflow but not function properly? Could it be a problem with the battery, the atomizer, or perhaps the cart itself? I'd appreciate any insights you can offer to help me troubleshoot and resolve this issue.
