Totally different ways of growing. With dirt you have a buffer between the plant and the fertilizer. A different chemical reaction with hydro than with dirt. That's why it's takes longer to kill a plant in dirt than hydro. With hydroponics you don't have that buffer so you see results immediately, good and bad.
You can use miracle-gro if you add what's missing. Calcium Nitrate and Magnesium Sulfate.
