Champion II seedling issue
I have seedlings of 6 tomato varieties and only the Champion II are having issues. The 3 plants are about 5 weeks old and are showing signs of wilt around the margin of the older leaves. These margins fold up eventually. There is also some growth distortion. I was thinking seed-borne bacterial canker since it's just the one variety with symptoms. There is no insect activity. They are under grow lights for 14 hours and are allowed to dry significantly between waterings. Temperature is 65 at night and 69 during the day with a heating mat under them.
