Organic and inorganic
Plants can only absorb simple inorganic compounds! They rely on bacteria in the soil to convert complex organic fertilisers into the simple inorganic chemicals they need. "Organic" farming by definition must therefore be done in soil. In hydroponics plants are directly fed the simple inorganic compounds they require, in the right proportions. So, strictly speaking, there is no such thing as "organic" hydroponics!
Plants need 16 essential elements to grow. Whether the source is compounded mineral elements processed and supplied in a perfect blend by science or from a cows p**p that is broken down by soil microbes and then absorbed by the plant roots makes no difference. Iron is iron. Molybdenum is molybdenum etc. The pathways from processed minerals to the plant are much shorter and more precise than the pathways from the cows p**p, and contain no potentially harmful pathogens such as bacteria, viruses and fungal disease.

Fertilizer is a substance added to soil to improve plants' growth and yield. First used by ancient farmers, fertilizer technology developed significantly as the chemical needs of growing plants were discovered. Modern synthetic fertilizers are composed mainly of nitrogen, phosphorous, and potassium....
