>>2325902 here, maybe you guys can help me narrow down where i should be concentrating my efforts here. i want to mix my own potting soil, but theres SO MANY soil ammendments out there and im unsure of what is worthwhile and what is just another overly expensive add-in.i started trying to learn about them but i feel a bit overwhelmed after seeing so many guides listing so many new things every time i read another.
a few that i saw consistently: sphagnum peat moss, perlite, vermiculite, pelletized gypsum, lime, and sulfter.
part of trying to learn to do this i learned there is 17 elements that plants need, which i would like to provide for them, but most things only talk about phosphorus, phospate, calcium, and nitrogen.
