Growing vegetables with hydroponics? List of veggies with recommended PH-CF-PPM

When growing with hydroponics there are many variable to  take into consideration when growing different vegetables, and some require  more or less of certain levels to be present in the water solution.These include PH, CF (Conductivity Factor) and PPH (parts per million) levels. These levels can be easily read with testing meters and adjusted according.
