Superthrive

Hello all i recently came across an article where it says superthrive was bad for veg. Does anyone know if this is true? I am wondering because my last grow i used it in the flowering stage for a while using the maximum dosage of 1/4 tsp/gl and i grew an autoflowering strain that came out amazing looking(link in sig) but smoking some nugs tasted kinda funny. But what i am wondering is if this increases the yield? i yielded over 2 1/2 a plant after 5 days of drying it and weighing it using superthrive during veg and a lot during flowering along with fox farms big bloom. Anyone have any input?

i dont see why it would be bad. ive used it seemed fine. if anybody wants to speak up im curious too. i have heard its not for flowering but in dont know why
