Anyonefamiliar with Liquid Earth brand nutrients??

I have just come across a line of nutrients by the brand name of Liquid Earth. Has anyone had any experience with them , hopefully comparatively speaking to others on the market? Are they suitable for a GH Waterfarm system or for that matter , any hydroponic system whatsoever? They seem to be the total package including calcium and magnesium as well as a good ratio of everything else. You guys are a great help to me and I thank you all for all the help you have given me through the years.
