IMO, the name of the game is going to be nano-batches with iterations.
Not to get too into the weeds, but it really depends on which preparation you are trying to hold. Like holding a tea is going to maximize immediate availability but is also going to keep brewing at some rate and your protozoa ratio is going to change accordingly, likely meaning over time your applications would have inaccurate benchmarks for microbe numbers at a minimum.
pH is both a game of attrition at the chemical level but organic matter complicates it, with most going to cause drift down and rather severely. moving into mineral source is so hard, as I know we touched on before...like UV and or acid and or heat/pressure applications are the only real way to get most mineral sources to comply with your timeframes
The only thing I'd be really able to work on you with would be stable hormone extracts/blends. There is a ton of commercial additives, even foodsafe ones, that can be used. Ethanol is effective for hormone solubility, especially in our ranges for even concentrated product. There is a ton of folks shoving hormones into the market and folks don't even know, having worked on bringing a product to fruition in this space, there are a dozen key phrases or more that are indicative of selling hormones under the guise of alternative extracts. Just about every nutrient company on here is also using hormones in their blends, unless they're AG salts or a base line only. Lab water, small amount of ethanol, maybe some poly80. The real nuance is in how you use it/describe it and knowing where to look to find said hormones. Honestly, with all the sauce I'd willingly message you Yan because you've always kept it real...there is one thing everyone should know...IF YOU ARENT RECOVERING YOUR OWN CANNABIS EFFLUENT STREAM HORMONES, YOU ARE TAKING AN L EVERY HARVEST!!! We should all not only be composting any cannabis refuse because of how well we feed these girls, but hormone ratios in a veg plant are.........good for veggin plants!!! and hormone blends found naturally in flowering cannabis is good for flowering cannabis. Do with that what you will, and protect your local water supply.
