I study lights, not nutes, but I do use them.
A little confused by the wording of the question.
Is this a single additive for bloom to be used with our regular regimen? or are you asking about a stand alone flower nutrient mix?
I'm not any help, but am curious all the same. I tried additives a few years back and found them disappointing. Science marches on and it has been more than a few years since then actually.
