250 ml solution #1
start with 200 ml distilled water and then add the following:
add 0.1g potassium sorbate
add 5ml white vinegar
add 2.58 gram MnSO4*H2O
add 0.5 gram Zinc Sulfate Monohydrate 35.5%
add 1 gram H3BO3
add 0.345 gram CuSO4*5H2O
add 0.1 gram Na2MoO4*2H2O
once fully dissolved, add more distilled water to reach the solution to 250 ml
250 ml solution #2
start with 200 ml (or little less) distilled water and then add the following:
add 0.1g potassium sorbate
add 5ml white vinegar
add 1.071 gram Fe DTPA 7%
add 0.208 gram EDDHA Fe 6%
add 0.2886 gram EDTA Fe 13%
add 25 ml from solution #2
once fully dissolved, add more distilled water to reach the solution to 250 ml
Dose 5 ml from solution #2 into 75 liter, which will give you the following ppm:
Fe 0.0333
Mn 0.02236
Zn 0.00467
B 0.00466
Cu 0.00234
Mo 0.001
3x weekly dose:
Fe 0.1
Mn 0.067
Zn 0.014
B 0.014
Cu 0.007
Mo 0.003
I usually don't go lower than 0.2 gram due to errors in accuracy but you can try.
