GMSgrowsanswered grow question 4 years ago I use Massive bloom formulation in flower along with my flower nutes. But the feed is only part of the equation and a small part at that. This is what plants need to grow their best. #1 Sun, get the best lights you can get, led are ok if you spend upwards of 2000 dollars, Hid is still the best for people without that kind of money to spend. The light is what allows the plant to create the sugars to grow. The better the light the better they grow. A cheap Hid will outperform a lower quality led any day. #2 is environment. Keep that as close to the humidity, warmth and c02 they require., then comes the food. With food, less is always best. Under fed the girls will still perform very well. Overfeed and the will suffer greatly and under perform on the flower production. Cheers
