Seems like a great line to be running with. I personally do use a schedule when doing living soil, my microbes get a regular and consistent boost every few weeks. Just remember that your living soil web usually lags about three weeks behind in delivery/accessibility to the plant. So, for example, when I would flush living soil (an artform in and of itself) the timeline would extend five or more weeks back from cut (stopping 5 weeks early, running the soil down three weeks, two week flush).
Don't overthink living soil. There is a ton of information out there but just remember that every little bit of dirt you've ever touched outside is living soil. Soil in the true sense of the word is living soil. Living soil in cannabis just means growing with normal dirt, and the mechanism of microbe consuming inputs and outputting your plant inputs rather than adulterating a molecule to a form which does not typically exist in nature just to ram it down the plant's throat.
Basically, you have some FIRE products you're working with. Living soil when done right will aid in natural pest prevention, natural pH control, natural heat resilience, and a minimum of nutrient inputs. Be sanitary if you are indoors (way easier said than done, trust me) and get prepared to fall in love with living soil. You'll quickly see why some of these old heads have 15-20 year old living soil beds that pump of flame. Anecdotally, the only crops I have seen lab results for in these parts over 4% terps EVERY TIME are the region's living soil kings (in a quad-state region).
