What is the best brand of cannabis fertilizer?

I have met and spoken at length with the Founder and Chief Scientist at Mammoth. They seem to have had a great deal of success with their product, which is quite unique and is used all over the world. It is used for all types of plants, but they seem to have had the best success with aiding in the growth of cannabis as a fertilizer. Their website is here : https://mammothmicrobes.com/mammoth-p/?v=7516fd43adaa
