A few years back I would mix about 1 teaspoon Grow Big + 1 teaspoon of Tiger Bloom per gallon of water. By the time I harvested, there was usually only a few leaves left. lol. I was naïve and thought they were just hungry. They were just getting smoked by the Tiger Bloom. Looking back now, I'm not even sure how the poor girls survived. I go with 1/4-1/2 teaspoon of Tiger Bloom and a full 2 teaspoons of Grow Big per gallon now. Still getting some discolored leaves after 65-70 days, but a lot of green leaves remain.
