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).
