As for the brands you have mentioned above, I'm not to familiar with them. I live near the coast in the northeast and buy locally produced fish emulsion and seaweed nuts. They all have different NPK values depending on the concentrations of fish emulsion and seaweed they use. The two that I currently use have values of 3-2-2, and 5-6-4. Don't be shocked by the low numbers. Seaweed is loaded with many other compounds that your plant will need. Every fall I go to the ocean and grab a truckload of seaweed for my veggie garden and my girls. I till it into the soil and let it do its thing over the winter.
