How can I save/salvage my tomato plants?

I've found that unless there's insect damage or rot, there are no harmful abnormalities. I've had tomatoes of nearly every size and unusual shape, and its just part of the unique beauty of nature. The best recommendation I can make on high yield is this. Insure your compost is fully decomposed before feeding it to your tomatoes, otherwise the rotting material will burn and rot your plants. Also if starting from seed I recommend starting them in pots to get them nice and root bound before transplanting. If you direct sow they tend to get viny and leggy and never really "bush out". Also the first time it tries to bloom try pinching the entire first round of blooms off. This forces the plant back into it's vegtative cycle temporarily making it stockier and bushier and also creates higher bloom production when it tries to fruit next. If you follow these steps your main concern will be supporting the massive weight of all the fruit (tie them up/cage them) and eating the fruit before they go bad. Now those sound like better problems to deal with right?

I don't know how to add a picture, or look at one either.

But I do know that water every day and too much feed will produce some of the most ugly cracked, thick skinned tomatoes you have ever seen.

The leaves probably have either Sun Scald or Late Blight, wait for you Early Blight..

Water a little less, feed a little less, BUT with the same food, worry a little less. You will have a much better crop. The other thing that you can do is cut out the SUCKER branches that grow in a V shape from the main stem, and cut the severely damaged leaves and put them in a trash bag and into the trash,

DO NOT put sick looking leaves or plants into a compost pile. They need to go to the trash

Regarding abnormality it could be"Misshapen or malformed fruit can be caused by cool weather occurring during fruit set or from herbicide exposure.

Catfacing is an abnormality that develops on the blossom end of susceptible tomato varieties. It results from cool weather at blossom time and causes the fruit to pucker and have deep crevices."

I think you are feeding them too much and pruning them too little. Though I don't live there, I have raised tomatoes in the past but do to droughts every July, have given up on the "hobby". Like you said, its expensive and time consuming'

Take your organic waste and dump it at the base of your plants .only water your plants at night.they should buck wild after that. With the waste egg shell peel bread crust every thing it like giving vitamins to diet.
