This should very well work out fine.
Even if the ratio is perfectly matched for N:P, the relative impact of P
relative to plant growth is nowhere near as problematic with N.
So running out of PO4 for a little while is fine. 
The K+ is in excess by roughly 50% which should account for slight water
change build ups and plant differences that might perefer more K+.

Yes.__Quite__ a bit in many cases.

This might be pH buffered since higher Ca is often, but not always,
associated with higher pH's.

I'll keep looking also.
