Hi Dale, Im a new grower but Im a student of chemistry as well. I was reading your journal and have spotted a problem and was unsure if you had identified it as well. Your water is very harsh for your plants, your ppm is very high and so is your pH. I know your adjusting your pH so thats cool but your starting ppm, alot of which is Ca, is causing a mag lockout. I would like to suggest to you that you either dilute your H2O with store bought distilled water, buy a distiller or RO.
I have the same issue as you but not as bad 500ppm and pH of 8. I use a gravity filter on my tap water cost about $15 just put it on the shower head and that gets rid of the larger molecules and sediment then dilute the tap 50/50 with distilled water from the store my starting ppm went from 500 to 150. Then I suppliment the H2O with normal FF nutes plus MgSO4 to balance out the Ca that is already in the water. The yellowing on your leaves is definately Mg deficiency caused by lockout.
Im pretty new to all this so please take my words with a grain
Much love brother hope to see another journal soon.
