What is this sold as? Is it for hydroponics? House plants? Greenhouse production? Some other crop?
What forms are those minerals? Are they chelated? or the sulfate forms? Some other form? Given the high % of sulfur, it seems they are the sulfate forms.
Compare the levels of this product with the ingredients in Nutritrace CSM+B. Old posts will list it as Plantex CSM+B, but I do not think the formula has changed. CSM+B has mostly chelated minerals. This means they will remain available to the plants longer than most other forms.
It may be safe to use if you dilute it so that no one ingredient is higher than the amount you would get from CSM+B, but would that make some of them such a small dose it is not worth using? I agree the ratios look wrong.
