I would think with all that salt that you would have very early yellowing Like it should be when finished. Demimished yeilds from improper nute uptake also.

I had a water softerner before chlorine water. Had to figure out it was the salt then switched to county water and the chlorine is even worse here. Actually here they are using chloramine as is doesn't evaperate like chlorine so no good chemicals lost in the lines and letting it sit out doen't help.

Are your plants a light green or a nice not to dark but dark enough green ?
