I been picking up stuff here and there.. About 15 gallons of soil I will be reusing.
If I were you I wouldn’t add anything other than what the recipe calls for. I don’t reuse the mix (other than into the garden, flowerbeds/pots, etc.). To reuse it would include work to figure out what to put back in. Taking away from the laziness of it all.
I would think you would want to run it as called for, at least a couple times before adding anything else. It is a “water only” recipe. And if your concern is in burning your babies, then definitely hold off on adding anything. I have found the mix to be generally tolerable by the great majority of plants grown (even once dropped a jade plant into it). And I can say that years ago when I did mix blood, bone, oyster, kelp, green sand, vermiculite, etc., etc., trying this and that soil mix, I found (roughly) the same percentages for expressions from seed that weren’t generally happy and satisfied as I do now in this mix, which isn’t as much work - and showed (roughly) better percentages.
No reason you can’t mix it in halves, that’s what I do.
If running from clone, doing what you’re looking to do will be much easier than running from seed. I run from seed; which makes "dialing-in" a bit tricky. But the mix is a nice palette to work from.
Have you considered going no-till? If I wanted to “reuse”, I think that would be the ticket - but not as easy as mixing a few bags together.
