This X Nutrients Calculator will calculate the necessary amounts of hydroponic nutrients to use in your soil or hydroponic gardening system. Choose between a basic or advanced program. You can specify your reservoir size or your watering container for soil. The calculator will give you step by step amounts per week. Always make
sure your pH is adjusted between 5.5 to 6.5. Never pre-mix, rather add the necessary amounts to your reservoir or container.
