Hydroponics = the science of growing plants in liquid mineral systems.
anything grown in soil (i.e. dirt) is not hydroponic.
By your defination everything is hydroponic, because all plants use water.
Again Hydroponics is the delivery system. It refers to the plant medium and method such as Expanded clay, rockwool, flood and drain.
When you water your plants you are providing them with nutreints
Nutrients are classified in 2 ways Mobile and Immobile.
Moble nutes move freely around the plant as they are needed. If you have a nitrogen difficency, the lower leafs will release their nitrogen and move it to the upper leafs (clsoer to the light). The bottom leafs turn Yellow.
Immoble nutes never move and stay where they are.
Macronutrients are NPK
Nitrogen Potassium and phosphorous
Micro nuts are everything else
(Macro)
Nitrogen moble
Phosphorus moble
Potassium moble
(micro)
Magnesium moble
Zink moble
calicum Immoble
boron Immoble
Chlorine Immoble
Cobalt Immoble
Copper Immoble
Iron Immoble
Manganese Immoble
Molybdenum Immoble
Selenium Immoble
Silicon Immoble
Sulfer Immoble
Reguardless of what bottle it comes out of this is what every plant on the planet need to survive.
Hydroponic solutions when mixed with water deliver the items to the root systems. It dosent matter if it went through a pump and filled a table, or through dirt.
With soil you would water with something like this once a week and regular water the rest of the time. This is standard practice around the world. I didn't just make this up
