Thanks for sharing that Ray. That is helpful.
For comparison purposes, and to show the range of variation across kelp extract products, I thought it might be useful to post a link for the Growmore brand I use:

Many of the same components are in both products, but with some variation in concentration. I would not be surprised if the variation is related to where the kelp is harvested, or kelp species, but don't really know.

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