Compare the pattern, not one moment
Note whether the plant recovers later, where the sun falls and whether heating or airflow changes during the day. Check the root zone before assuming every wilt is caused by dry soil.
Keep the plant identified and record changes rather than adding water repeatedly to a wet pot. Persistent decline or a soft base warrants closer inspection.

Does afternoon wilting identify one disease?
No. Timing is useful evidence, but it does not establish a diagnosis alone.
