Thank you for your answers :) So, i checked, a us gallon of water equals about 3.8 liters. If i measure A+B 10ml each per 10 LITERS, it's 3,8ml A+B each in a GALLON. If I measure 6ml of A+B each per GALLON, it equals 15.6ml/10 LITERS, of each A+B. So i'd be adding more nutes? Or did you mean 6-7...
