Superthrive while flowering?

I tried running a search and couldnt find anything, sorry if this is rehashing a common quaestion but, Superthrive during flowering? Yes or no and how much and when? Im 25 days into flowering.This is my first grow, sorry for the noob question....

ive heard 2 different sides. some say its good because they just dont see any negative effects from using it but ive also heard that the hormones superthrive has is meant for vegetative growth...I use it anyways...
