When Fertilizing a Plant it is important to understand the Basic Elements seen in the Periodical Table of Elements, and how they related to the Health of your Plant. In Ancient Times this was called Alchemy, and these would be classified as Alchemical Substances, even today, like Alloys, but Atomic and Molecular. Plants were thought to respond not to the Sun, but the Planets, which are associated with various Gemstones and Metals as in the Chakra system; this Planetary Planting schedule can still be found in the Old Farmers Almanac.
So when Feeding Elements to your Plants, Chelated Metals are best, we bought Chelated Metals for ourselves.
