Using your salts, I want to duplicate the following formula. How much of each do I add together to make the following: 10.5% nitrogen, 3.2% potassium, 2.3% calcium, 0.6% phosphorous, 0.09% magnesium, and 0.02% iron

I don’t think you can make a solution of 10.5% N from kno3. You would have to use other fertilizers and I haven’t seen a calculator that can do that. It would acquire a lot of calculations and trial and error to accomplish that.
