Well, if the liquid is 3% N in the bottle (30000 ppm), and the gallon is
768
teaspoons, then adding 1 teaspoon to a gallon of water gives 30000/769 =
39
ppm N (my calculator rounds it to 40), so 100/39 = ~2.5 teaspoons.

The question is not in the calculation, it's in whose recommended dosage
rate to trust!

That's what I meant, if the dosage recommendation was right. I'll give it a
try.
