You said you had a bit of natural clay and shale in your mix right?
I do know clay and shale likes to perch, and hold onto calcium and potassium more then other compounds, and that can cause alkalinity and lockout issues over time slowly. It's the reason house wells set into shale bedrock have so much calcium and potassium in their water actually. Clay shales also hold onto fossil fuels and leach sulfur into the well aquafers too. Thats why many house wells drilled around here in the mountains have super alkaline, calcium and potassium hardened water that smells like boiled eggs. Not sure how that would affect a soil mix in a container though.
The super alkaline, hardened, boiled egg water is also common around the great lakes, and near the more mountainous internal regions of Cali and up through the cascades.
If you can keep your PH in check (6.5-Neutral in this context), even if plants can mange the higher PH unamended, all the calcium, silica, sulfur and potassium in that clay and shale will become plant available over time with healthy root bacteria and fungi breaking it down btw. Becomes a slow steady release of bioavailable mineral content.
