Actually, that information is incomplete.
K-L-N contains about 0.05% IBA, about 0.10% NAA, and 0.025% B1. The plant food ingredients (N, P, & K) are not a fertilizer, but a remnant of the compounds used to get the hormones in solution. IBA and NAA - by themselves - are not very water soluble, so they are introduced as mineral salts of those chemicals.
At 0.009-0.011-0.006, when used at the recommended 1 drop-per-gallon rate, that's equivalent to adding 0.0015 ppm N fertilizer - next to nothing.
SuperThrive - from a hormone perspective - only contains NAA, at about half the concentration as K-L-N. It also has about 0.09% B1, plus a wide variety of other ingredients - kelp extracts, humic acid, iron compounds, etc. - which might be of some benefit, but that begs the question of how much benefit at such low concentrations - again considering the 1 drop per gallon use rate. I'm sure it also contains the "plant food" components, but the "Vitamin Institute" has chosen not to publish than information - nor a MSDS, for that matter - while Dyna-Gro does.
