I've got a kelp based KNF extract that I use as part of my veg nutes but I was wondering more about mixing kelp into the mix as a significant component as I think it high in K as well as many growth hormones and all the trace elements you mention.Kelp is always good.. It has something like 60+ trace elements and all kinds of goodies. Kelp should be cooked first as well. Adding it raw or unprocessed can overwhelm the environment
