No Ca or Mg? Wouldn't tap and rainwater water, which is what most gardeners use, fix that? Plus I also thought MG uses MicroMaxx, Scott's time-released micro-nutrient fertilizer. IDK, I've used MG many times without any problems.
I don't care for Scotts, the company that owns Miracle Gro, and how they operate, but I could say that about most of the hydroponic companies that are advertising to cannabis growers (cough * Advanced Nutrients * Canna * General Hydroponics * cough).
I'm in the west coast and Kellogg is about as local as I can get short of sifting my own soil and composting myself. I like their soil and I like their organic fertilizers a lot more then Miracle Gro. Lilly Miller, the company that makes Alaska Fish Emulsions is also a big favorite of mine. Kellogg's All Purpose Organic Fertilizer (4-4-4) is $6 at Home Depot and Lowes. They also have a tomato blend for anyone looking for an extra bit of nitrogen. Alaska Fish Emulsions (5-1-1) only cost $6 and their MorBloom is $10. A little more expensive, but really good stuff when used on native soils or with organic potting mixes.
