B'Cuzz Bloom Booster Any Good?

Been given a bottle by a guy whos switched to coco and doesn't use soil ferts anymore.
The directions are that it is to be administered daily during flowering, so it doesnt seem to be macro-nutes?
I'm currently 26 days into flowering and just beginning to increase from about 2-3-2 to about 2-4-3. Should I be using his bloom booster too?

ttt. I've tried googling, but I'm none the wiser...:wtf:

ttt...anyone...

pretty much any bloom booster is better than no bloom booster. give it a try
