Most likely either your pressure is too high, or your injection system is shot. Which Fertigator device do you have, and what is your supply line pressure. If your supply line pressure hasn't changed recently, you can pretty much rule that out. Check all of your wiring, maybe the Fertigator unit is not functioning at all. If you know the wiring is OK, and the system is fertilizing properly, I would double check the unit it self. Make sure there is no clog within the supply line or the mainline pipe itself. Let me know what you find.
