The search result below that one was for a different brand Masterblend Tomato Fertilizer 4-18-38 https://www.morgancountyseeds.com/pr...lizer-4-18-38/

I also found this site along the way http://www.tomatoville.com/showthread.php?t=37818

HG is the most popular commercial growers blend I have found, the formula is precise. If you ship a 25 pound bag ship it in a flat rate box, I have shipped many that way clear to AK. One bag will do about 2500 gallons of water, you must also add CaNO3 and MgSO4, just follow the directions. If that is too much, check out their Hobby Blend, you only have to add MgSO4. We use injectors, but a two tank system for hand mixing works too. I have tried one tank, mixing one at a time, but I still got P precipitation.
If you learn this method of fertilizer programs, you will never look back. I used to grow in dirt, raised beds, this and that, and will never look back. I do this to make money, so I want results, taste, yield, efficiency.
Good luck Robert
