Calibrations are not in Gallons per minute but number of gallons per 1000sq. ft.
I generally apply 4 gallons of mix/1000sq ft. Select the proper tip to fulfill this at about 60PSIG (FERTILIZE) and higher for your herbicides at the trigger. So 100 gal tank will spray 25,000 square feet of turf with properly weighed fertilize.
