Hydroponic Nutrients

The purpose of the hydroponic nutrients is to supply the base elements (Nitrogen, Phosphorus and Potassium) to the plants. These macro-nutrients are essential; you cannot overlook them. Many products out there have other elements except the N-P-K, notably some other macro-nutrients or even some miro-nutrients (you will see them called trace elements). 

If you want to read more about macro- and micro- nutrients, go to my post on the 12 Plant Nutrient Deficiency Problems and How to Fix Them, where I explain the importance of each element.

In any case, you must provide the base elements first (N-P-K) and then select the supplements to enhance growth, health and ultimately yields.

I have reviewed numerous nutrient products, i.e. fertilizers, with such variant characteristics that I had to dive into analysis of their actual content in the active ingredients.
