You need to reread what I posted and compare it to the specs of your softener that you posted about the capacity at whatever salt dose.
Then stop using softened water for irrigation. BTW, too much chloride kills vegetation.
Thanks, I used potassium because the plumbing company that gave me a quote when I wanted to install a water softener wanted an extra $400 to plumb the back yard separately so softened water with salt wouldn't be used on the hose bib. They said to just use potassium and it's actually better for the plants to have softened water with potassium rather then raw water.
I wish I would have been more educated about softeners when I fist wanted to get one.
