1) What is the final concentration you're looking for?
2) What is the injection ratio of the Hozon?

If we assume 125 ppm N and 16:1 (my current feeding rate and the ratio of an
old Hozon I once had), then each gallon of concentrate will make 16 gallons
of final product, and the concentrate must have 16 x 125 = 2000 ppm N.

Using the calculator at www.firstrays.com/fertcalc.htm, we see that 1
teaspoon of 30-10-10 provides 396 ppm N, so your concentrate will need
2000/396 = 5.05 teaspoons of fertilizer to make of a gallon.
