Nutrient Solution Formulation for Hydroponic (Perlite

Formula 4 uses potassium nitrate to supply all of the K. One potential problem in this formula is that large amounts of N are also supplied with the potassium nitrate and this restricts the amounts of calcium nitrate that can be added. Reducing the calcium nitrate too far might lead to BER unless the well water is supplying some Ca. Supplying some
