That nutrient ratio is a bit geared toward K... if you want vegetative plant growth it should be more balanced toward the N side...
I would switch nutrients out and pinch flowers and fruit if you want bigger plants in the mean time...
I dont know about 1lb per 600' row you already added... if anything i would only add more nitrogen, but maybe wait to hear from some more experienced gardeners first, you definitely dont want to over fertilize...

Thanks Rancher! Good point you can always add more but can't remove it.

Like you suggest, I'll look forward to other folks' comments too, and work on getting that soil test.

The tomato plants which are in a row 4' away have doubled in size to 24-30" since being put in the ground, and the Beeksteak plants have golf-ball sized green fruits. Prior to being plowed & tilled this spring, this was a horse pasture for many years.

At this point I would not add anything, I would pinch off the early flower buds and peppers, and leave the next flush alone. Give your plants a week or two of nothing except water if needed. Get the results of your soil test. If it used to be a horse farm it may not need hardly anything as the soil is probably nutrient rich. After the week it two the plants will give you the answer you are looking for.

AmericanGardner, where are you? (No, "United States" isn't good enough.)
