Dude... get floranova series. You don't have to mix up 3 different parts to get going. With flora nova, all you do is just mix the grow with the water and that's it. When you get ready to bloom, You do a 1 week transition feed of both bloom and grow with a 50/50 mix. Then go straight to bloom feed. Only have to mix 1 part most of the time. Flora series is more time consuming as far as mixing your nutes. I have used both and prefer the floranova. Also there is more stuff in the floranova nutes for happier plants
