im using areo/sprayer.. are you sure it's per gal? i'd use my nutes up in two weeks if im going to be adding that many teaspoons each time... fuck that,. the plants are going to have to settle for 1-2 tsp per 10 gals.. there is no way im going to be adding 1-2 tsp per gal..
for nutes im using technoflora (grow, bloom, boost).
I'm positive its per gallon, how would the people who make that food know if you have a 5 gallon or a 500 gallon reservoir?
Feeding at 1/10 of the suggested amount will probably keep your plants alive, but they'll be begging for more i'm sure.
You should really get yourself a TDS\EC meter and go by that, and of course by learning what your plants are asking for by their body language.
Fucking plant food just flys through your hands, but its part of the deal unfortunately.
Personally i have one (soon to be 2) 20 gallon reservoir and i use a full $14 bottle of H202 every 2 weeks or so, and my nutrients don't last much longer. If there is one good thing i can say about soil (theres a few, but this is one) is i used as much nutes in a year of dirt-baggin' as i have in a month of hydro.
