All the things you have on hand except for the blood meal are low-dose fertilizers. All of them are basically single-nutrient fertilizers. And all but maybe the liquid fish stuff are very slow acting and it may well be expired.

It sounds like your plants need a "quick fix", something fast acting and well balanced with all the nutrients as well as fairly high dose. If you aren't opposed to using synthetics then Miracle Grow All Purpose water soluble fertilizer is your best bet to save them now. That approach will then give you time to side dress all the plants with some of your mix you have used in the past. If you don't know how to side-dress plants lets us know before doing it.

If you only want to use organics then you'll need to pick up a fresh bottle of Fish and Kelp Emulsion blend and use it weekly until the plants begin to show new healthy growth and then side dress the plants with your mix.

I'm a little surprised that your tomatoes look very sick, especially when you've been putting slow acting fertilizer on the bed in previous years. Does the bed have any organics in it? Added compost, etc? Tomatoes won't optimally thrive without added fertilizer, but they won't be dead in a month. I've grown tomatoes in nothing but compost-amended soil, and they do well. You might think harder about what's different this year.
