Because of the cost factor I am going to use commercial grade
nutrient solution this season. I bought a 25 lb. bag of Hydroponic Special 5-11-26 for about $30.00 which makes 400 gallons of nutrient solution. I still have to add Calcium Nitrate and Magnesium Sulfate to that to get a balanced hydroponic solution. See chart below. Ron
