A milligram scale costs like 15 bucks. Making A+B stock solutions is very easy. (Easier than driving to the hydro store).Being this exact is even beyond my abilities. Wouldn't you have to weigh micromoles and such? I like to have more leeway. However I can see those who know how to use these being able to really tighten their margins and increase yields as they see fit. I am using organics chelated by Aerobic anoxygenic phototrophic bacteria.
I just measure those ingredients into either A or B stock solution and use 10mL of A and 10mL of B per 1 gallon of final reservoir nutrient solution. It's not hard, but people with no experience or knowledge of this method come up with all sorts of reasons why this is too hard. (usually strawman)
