Terpinator (During Flush or Not)

I’m a newbie using terpinator and only on my second grow overall so I realize I’m not bringing a lot of experience to the table when answering, but my plan was to use it until the final week when flushing. They recommend using during the entire life cycle of the plant. If it does help with terpene production then I want to get as much out of it as possible especially towards the end of flower. Good luck on what you end up doing!
