Build A Soil 3.0

Hello out there. I am considering buying some BAS 3.0 but had a few questions for people who use it. Do you need to add additional nutrients after a few weeks? Any problems with pests from the living soil? What do you wish you knew about it before using it for the first time? Any help would be appreciated. I follow the YT channel and like what they do at the company, just trying to learn more about keeping a living soil happy and things to watch out for.
