Is fertilizing tomatoes with Tomato-tone and fish emulsion a good practice? I've been doing this once a month, but read on other websites to do this twice a month. Also, is there a point in the growing season that I should stop this process?

Hi- these fertilizers are fine to use if needed. If your soil is high in organic matter you may only need to fertilize lightly at transplanting to help plants get established, again when first fruits are marble size, and then once more 2-3 weeks later. If soil fertility and organic matters are relatively low, once a month would be sufficient, unless you see signs of nutrient deficiency- leaves off-color and plants growing very slowly.
