I hear ya. I say if it works well for you change nothing. Its all very subjective, from one user to another, so if you and yours love it you're doing it right.
I know that no matter what we add or trick to a plant will grow to its weakest resource. No matter how much nutrient is provided
for instance high temps will always adversely affect results and more of anything but the needed resource wont help that issue.
I like organic bio stim, and I know it occurs naturally in healthy compost so thats what I use. I got no knowledge about bottled ones, though I did use, until it was gone, two bags of beneficial bacteria(forgot the names), but havent for years. I saw no difference with the addition so I didnt continue. like when I add calcium, or sulphur, or anything now my plants fail. I think I'm at a sweet spot in soil.
