well im not a fan of perlite and if you are no-till or recycling soil i recommend not using perlite or vermiculite etc. im sure some ppl will chime in and sayy rice hulls etc, but i havn't used them plus they will break down over time and then you have the taskk of keeping up with the right viablle ratio, just my opnion. i am also sure ppl will disagree with what i do mysell which is use my own variation of a basic coots mix, but i use coco instead of peat or shagnum. here is how and why. on it's own coco is basically the perfect medium water retention and for ph. i basically use really high grade organic compost and castings, not commercial castings fed shit or store bought compost. ik what is in my compost and it's allot of coffe, bannas egg shells as well as my chopped fan leaves etc among whatever else i eat that is compostable, worm casting the same. store bought castins are fed an undiverse diet. anyway i needed to make this point because the idea is to use as little organic matter as possible yet still have enough food, microbes etc and balanced for micros etc... i cannot give you an exact ratio but it's possible 50% or more coco, th result is a very dark rich yet fluffy mix that holds water and air grea even in small or fabric pots that in the past i've had to water frequently with other mixes. to this base i also mix in bokashi, azomite, langbenite, alphalpha meel, neem meal, kelp meal as well as some guanos i use 3 kinds of guano with diff NPK, however i don't put a ton in the mix as it is largely soluble. the other part of the regiment is nute tea as needed not often at all and/or top dress when you up-pot. i use diff top dress ratios of the mentioned DTE single ingredient nutes(alphalpha, kelp and guanos) and which guano depends on if it is veg or flower but always a bit of the others to maintain microbe diversity. i never water with a true compost tea as that also will throw off microbes not simply add more like ppl say/think. you can spray compost tea on leaves in veg tho for overall health, but don't foliar the nute tea it will slow root growth. this is pretty much what i do in a nutshell it may sound liek allot or confusing but it really isn't. i do this becasue it is easy once it is made. i keep huge 100 gallon plastic bins and when i harvest i throw rootball and all back in there slightly reammend and mix. this last part has some nuance that would serve to confuse so i will leave it at that, but basically i sometimes don't re-ammend the entire bin but top dress the next wave, this is really on a case by case basis but you will get it.
to clarify a guano tea is a nute tea, a compost tea is well made with compost/castings and is about microbes not soluble nutes like nute tea. also to adjust the tea npk use othe DTE single ingredients based of need, just pay attention to the soluble unsoluble ratios and do the math
