We have very high pH here as well. Mid summer about 8.3 pH in tap water. Even though there is magnesium in the soil, the high pH messes up the plant's ability to uptake the nutrients

I get it--that's why I think the tons (literally) of organic material helps mine so much--makes the soil easier for the roots to grow in (lighter, loser, water can penetrate and drain) and drops the pH a just a titch so that the minerals already in abundance are more available to the plant, plus the bonus of additional nutrients. Of course, I have to keep adding it...
