Thanks!

Sorry! I missed this post.

So far, the only statements out of the manufacturer are that the product "has been shown to contain a large number of auxins, cytokinins and polyamines, abscisic acid, and concentrated gibberellins and brassinosteroids, which have been shown to elicit a wide range of physiological responses including cell division, stem and root growth, flower and fruit development, seed yield and protection from stress."

The SDS says nothing about the exact chemistry. Otherwise, I only have the following contents (ppm):
