I can tell you for a fact that using superthrive will cause you to have more males when growing from seed. Its been studied time and time again, and if i can find the link to it from the old OG FAQs then ill post it. Its only to be used if a plant is dieing and you need that extra umph to bring her back. But I would not use it if i were you. I have it at the house, but I only use it on dieing plants... house plants at that. hope we helped, laterz.. Oh and yes it taste like shit, just for the record.
