I am not sure if I am remembering properly, but I thought I heard something about too much cal/mag or pK can cause what looks like an N deficiency by locking it out. I forgot if it was the cal/mag or pK though. I have had a similar problem with a sour diesel I was running. It had the same leaf splotchyness. It however didnt affect growth or quality though.
Either way, I would aerate your water for 24 hours before using it or even mixing your nutes in it. There is chlorine in tap water and the oxygen helps push the gasses out of it. I honestly think it is to much magnesium locking out N. Where are you located? You can always google the water quality in your area and see if maybe there is a higher than normal amount of Mg in it. Either way, they arent looking that bad.
