You can analyze and isolate the Ca and Mg, but it's not likely you are short on Ca, so adding some Mg is about you'd like need to do. If the Gh was like 3 or less, then perhaps.
More trouble than it's worth for most folks.
K+ will come from the KNO3, you have plenty relative to N with KNO3, about a 4:1 ratio of K to N as far as plant demand.
So adding more is not going to hurt nor help.
GH booster is about 40% K2SO4 anyway.

Tom,
OK I have quit using k2S04, and increased KN03 from 1/4 to 3/8 tsp. I'm still dosing KH2P04 at 1/16 tsp. And of course dosing 1/4 tsp CSM+B and 1/16 tsp Chelated Iron on off days. I haven't got and Grumpies GH booster or any Chechums yet. Is this ok, or can you predict a problem.
Thanks
Joe
