Argus watering system

Hey yal’ll! I work for a large cultivation in Arizona. A few months ago we got a Argus to automatically make our feed tanks (four 1,500 gallon tanks) but have yet to actually use it cause they cant seem to figure out how to use our formula and fill at 200 gallons a minute. they keep coming up with excuses on why its not working and is now trying to get us to run it at 50 gallons a minute after being promised before we bought it that it can with our formula do 150-200 gallons a minute. we have ran over 100 tests with it over about 5 months and still haven’t made progress.

curious if any of you guys have a Argus/know someone that does and if they have had a similar problem with them? or maybe have some tips on the system.
