My mistake. Sorry. All sorted. My spreadsheet had a formula error.
I have a question regarding HYG-1437 Agricultural and Natural Resources Sep 19 2018 (Hydroponic Nutrient Solution for Optimised Greenhouse Tomato Production). https://ohioline.osu.edu/factsheet/hyg-1437 There appears to be quantitative errors regarding the amounts given for both Boron and Molybdenum. Boron Table 3 says 0.4 ppm. Table 4 says 165.9 mg/L in concentrate (Cx100) of Borax. Borax - Na2[B4O5(OH)4].8H20 provides 11.5% Boron giving 0.0191 ppm in dilute solution which is only 1/20 of Table 3 stated 0.4 ppm. Molybdenum Table 3 says 0.05 ppm. Table 4 says 12.6 mg/L in concentrate (Cx100) of Sodium Molybdate. Sodium Molybdate - Na2MoO4.2H20 provides 39.7% Molybdenum giving 0.005 ppm in dilute solution which is only 1/10 of Table 3 stated 0.05 ppm. All other elements balance out exactly within the stated concentrations. Are the quantities given correct in Table 4 and Table 3 concentrations incorrect or visa versa for Boron and Molybdenum?
