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!

Dave Neal (D-G) has long recommended low fertilizer dosages, feeling that it
spurs on more root growth as the plant "reaches" for more food. The folks
at Texas A&M, Blackmore Co., and J.R. Peters all have researched and/or
recommend 50-100 ppm for continuous feeding (every time, as in S/H), or
100-200 ppm for periodic feeding (such as every other week, with fresh water
in between).

Over the last year, I have been using around 125-150 ppm at every watering,
and am quite pleased. I do drench the plants pretty heavily via an overhead
misting system in between sometimes, so I'm probably knocking back my
overall concentration a bit in between feedings.

Okay, I gave it a try. I use Dyna-Gro Bloom (3-12-6), and even at the
lowest level of 100 ppm, I get 2 1/2 tsp., well over the 1/4 - 1/2 tsp.
recommended. That sounds scary to me. Is this right?

ve, therefore,
simply enter the
"N" value from the fertilizer label and the desired nitrogen loading in
ppm,
and it tells you how many teaspoons to add to a gallon of water (and
milliliters per liter).

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