For a quick, decent, inexpensive off the shelf solution, you can pick up Espoma Tomato-tone or Vegetable-tone from Lowes or Home Depot. It has a decent ingredients list so it's pretty well balanced.

Otherwise a more recent product that people have been talking about is Texas Tomato Food. It seems to have everything it, and is a little more geared to the pod producing stage. 256:1 concentrate ratio and free shipping clinched it for me, i ordered a quart of it the other day.

I linked the Texas Tomato Food product below. If you want to check out some online discussions about it, search Google and you'll see some discussion forum links (i just checked). I have zero affiliation with the company btw, i was just surprised by the ingredients list and the price, products with these ingredients usually cost a lot more.

How about those worm castings you have?

Fish emulsion, blood, cottonseed, or feather meal for N. Bone meal for P. Kelp meal for K. Bat guano. Some more aged compost if you haven't mulched yet, worm or compost TEA if you have.
