I have three tomato plants, 2 cherry and 1 regular. The regular tomato plant has suddenly started wilting a lot. I was fairly certain it was a watering issue, given the heat and the fact that it recovered last night when it got cooler. However after dumping tons of water on it over the past 24 hours it hasn't perked up. Plus the other two tomatos in the same raised bed are doing perfectly fine with no watering at all. There doesn't seem to be anything on the leaves indicating a virus or bacteria.
