It's hard to tell if there is any real benefit or not but early test show it may be. That's all I can say. It is used more as a quicker way to sex the plant but if it shows the sex earlier then it flowers earlier too. Earlier flowering means more time to produce resin.

The most importing thing you should know is it takes 5-10 day's for the plant to change cycle from vegetation to flower so the nutrient requirements will not change to flower cycle nutrient on day one.
