My point being, for most of these vendors to pass off a "Grow" food of say, a 3-5-8 is ridiculous. The N and K values are always reversed for some strange reason. A good "Grow" food is more like a 30-10-10, 18-5-9, or a 9-3-6.
When I amend my potting soils, I never add anything that includes K, like greensand. The plant gets all it needs from the compost.
