Buck, I can see where Rex is coming from. In Onyx sand which has a much larger concentration of a specific macro, say potassium, when compared to flourish tab, a millionth of a percent, what would the root tab do that the onyx sand isnt doing, with respect to supplying potassium. IMO, when planted in specialized substrate, root tabs benefits may get masked, as opposed to in inert substrate where the benefits of root tabs cannot be disputed. But that being said, the guarenteed analysis of the specilized substrate is a bulk measure, rather an average, whereas in the root tabs, you are right in saying that it is more of a "point" measure.
