Interesting, I've taken better photos of the leaves and tried cutting the stems in half to see if there's anything, but forum software may be resizing them to be of much use. I'm not sure I do see anything conclusive?

Is it possible this is fertilizer burn?

Several of the tomatoes impacted are supposed to be resistant to fusarium wilt, but I guess if the plant wasn't strong to begin with, it could have helped it set in?
