Help! Most of my tomatoes are dying :( Pics

Most of my tomatoes look diseased this year. It has been wetter than normal recently. They are in raised beds, no additional fertilizer other than compost.
Any ideas? Do I have more than one disease? Thanks in advance for the help!

The photos are not enough to say for sure all the things that are wrong, but here is a start. Some of them are showing early blight, some show specks consistent with septoria, some look like fusarium. All of the plants show signs of severe lack of nitrogen. You have a nutrient imbalance that should have been corrected long ago. Also, have you been pruning the plants to a single leader?

Darrell - I was thinking poor nutrition was behind the disease. I am trying to do a better job of really reading all the information to come to the best conclusions and advice. Still such a newbie but I have learned so much from you, Dave, Carolyn, B54 and everyone else who shares their knowlege on these forums. Thanks to all of you.

Something I don't think enough people take advantage of it County Extension Agents. They can help with soil tests, usually where to find 'amendments' and local growing conditions. Years ago we moved from east of Richmond to Faaaar west, and it was very different. He was really helpful and actually seemed interested.
Anyway, I would start with a soil test. Don't give up!

I agree that there are several things going on in those pics but I'm also wondering, since they have obviously been in trouble for some time, what steps you have taken so far to try to fix the problems?

The reason I ask is because sometimes the fixes we try help but some make the problems worse. These are mostly beyond salvaging so there is much you can learn for next year from this experience.

So have you used any sprays of any kind? Tried a fungicide? Fed them anything? Compost is not a fertilizer. How deep in the bed? What is it filled with? etc.

I think maybe you all are right that its a nutrition problem. I used the square foot gardening mix of 1/3 manure/compost, 1/3 peat moss, and 1/3 vermiculite. I was under the impression that I would not have to add fertilizer with this mixture. I have used the diluted fish fertilizer once, but I had been reluctant to use regular fertilizer out of concerns that I would eventually get too much salt buildup in my soil.
Is that a valid concern?

I'm a fan of the square foot method, but I always use additional fertilizer even though he says you don't need it. I don't do my tomatoes in the SFG anymore, but I have plenty of in ground space.

Thanks for the info everyone. I will fertilize and report back if it was a nutrition problem!

Salt build-up is really only and issue with synthetic fertilizers and even then only certain ones of those (like MG). If you use organic fertilizers - and I definitely agree that Mel's Mix needs additional ferts - then it isn't a concern unless you get heavy into straight manures.

Organics don't act as quickly but they do work.

But note that no one said it is only a nutrient problem or that feeding them now will fix all the problems. It won't. Your plants also need to have all the affected foliage removed and a regular spraying program with a fungicide because of the fungus diseases you have.

And the one plant that looks like it has fusarium wilt (the last pic) needs to be removed completely. Check out the diseases Dar listed in his first post for further treatment recommendations.

Personally, since your zone has such a long growing season I'd replace most of the plants with new ones rather than try to salvage those in your pics. JMO

I forgot to answer the pruning: I did plant to a single leader (but I don't think I will next year!).

What fungicide do you recommend? I have a neem based one.

I did it once, so I knew it had to be possible somehow....
