Hey dude. I use that along with liquid karma. I used it for veg and flower because that was what i was told to do. I probably should of read up on it to see if it should only be used to flower. Either way I don't have a basis for comparison because its my first grow. I can say though that my plants seemed to have grown very fast, and at 25 days flowering they resemble other plants (that I've seen in pics) that are well into 30's and 40's days of flowering. Maybe I just got lucky on the strain though.
