Why Hydroponics Nutrients Don't Have Correct Labels?

What’s the Truth behind the Nutrients Labels?
Sometimes when you visit your local hydroponics retailer you unintentionally purchase products that give little or no truth about the actual ingredients present in the product. You buy them because they suit your budget. Sometimes if you have to choose between two products that have similar ingredients, you end up choosing the one that is less expensive. But, you don’t realize the truth behind this price difference, the expensive one had better ingredients. This is because the information given was incomplete because of the restrictions created by state regulators.
I feel like cheated when I don't get the correct information about hydroponics nutrients ingredients, as some times it leads to less yields instead of giving bigger and better yields.
Don't you feel cheated about hydroponics nutrients labels?

From what I have learned , you only need liquic kelp or liquid seaweed

Very rightly said by nancy jones, we all are been cheated and it is very important to check the ingredients used in the nutrients and have complete details about the same. Certain nutrients are suited for certain hydroponic mediums, but it is necessary to cross check the ingredients used in the products. All hydroponic companies don't give out complete details about their nutrients ingredients. Their labels are manipulated and it is because of the state laws regulation. Recently i came across an interesting update about the Hydroponic nutrients label accuracy... Thought might be helpful to others while selecting the nutrients required for their plants..
