hate to say it, but it doesn't look good - I'd say fusillium wilt (but that's a guess) - you definitely need to pitch them if that's the case and will need to sterilze that container if you use it next year. sorry

Well now, what to do?
I snipped off all the yellow leaves and then used some miracle grow liquid fertilizer on it. This was before I thought it was wilt. The remaining leaves have not gotten any yellower and new fruit is setting and the older fruits are starting to ripen. I don't have a pic right now, but if it was Fusillium wilt, wouldn't the whole plant be a goner by now?

I have tomatoes that look like this also. I think it's a result of too much fertilizer; most hybrids don't get fusarium wilt. I had used some granular fertilizer around the plants instead of the liquid fertilizer that I always use. I am going back to the liquid and hoping that we have gotten enough rain to wash away the other fertilizer. Sounds like a strange year for tomato growing.
