I donâ??t know, I am just speculating but these ferts are created for cannabis. The given concentrations are for cannabis and the ratio changes every week so why would you not trust these measurements.

My understanding was that the ¼ rule of thumb was for nutes not intended for cannabis. As cannabis generally doesnâ??t like strong nutes (I would assume this is taken into account by the hydroponics companies)
