You can decide for yourself after you've grown, but here is where I differ from the people using these kind of nutes. IMO, all those expensive "bud enhancers" and special "big bud nutes" are bogus and a waste of money. nutrient companies don't get sued over them because they put just enough NPK in them that you can't say they do nothing. At one time, they were putting some very potent hormones in these products, but they were eventually banned for plant use.until someone shows me a controlled experiment with side by side tests, I will continue to call them bullshit. No one has proved it yet!
but.. but..but...now we'll get anecdotal "evidence" saying they do work. Well, all I will say further on this is, do your homework! The reason they don't work is you can't force feed a plant. Adding extra nutrients that plants are known to use during flowering won't make them grow anything bigger!
Plants take in what they need, as they need it and adding these "enhancers" is one of the causes of "salt" build up during flowering. They also won't hurt if used at low doses, so you may as well use what you bought.
Realize, I'm not trying to discourage you, only steer you down a path based on science and fact. Be aware however, I've been told right here on this forum, that science doesn't trump anecdotal evidence because Joe's uncle's cousin's friend once grew the world's largest bud using Bud Exploder............
Here's another myth to beware of:

Now you're beginning to see why I'd hoped to steer you onto an organic path, no mixing, measuring, ph tests, ppm or EC are irrelevant,etc. Mush less complicated!
But done, right, using manufactured nutrients can and will grow great weed! The two biggest mistakes new growers make are over feeding and over watering.
If you are considering getting a book on growing Cannabis, I highly recommend Read Spear's: Cannabis cultivation Reconsidered: The Science and Techniques for Huge Indoor Yeilds.

Unlike Jorge Cervantes or Ed Rosenthal, Read isn't afraid to call BS on garden myths, he spells out the scientific reasons why they can't/don't work:
