Extreme hardness in your tapwater IS a potential cause of nutrient lock-outs.

I'd flush your plants with a VERY weak solution of humic acid (Soil Syrup) and until you can get a better water source, check out a hard-water formula fertilizer. There are a couple out there. But you will need to deal with this if you are going to continue growing. Are you seeing calcium scale on your ceramic bathroom fixtures?
