Currently I'm using a 10:1:10 N:P:K ratio that seems to work
well. I guess if you're not using KNO3, you can test your Nitrates,
work out the amount of N in ppm, then add in the appropriate amount
of K, you'd be in the ballpark.

even if it doesn't need to.
It is my opinion that there's a K+ / Ca++ relationship. They need to be
in a certain ratio or range in order for K not to block Ca. Note, this is
my OPINION, and I'll be rearching this in the next few weeks to determine
the exact nature of the relationship - if infact there is one.
