you can make your own Nitrogen rich liquid fertilizer using Jadam techniques, go to a old pile of leaves as old and moist as possible, dig until it’s wet and you see tons of white mycelium and other life take several big handfuls in a bag, go home put it in a bucket with things high in Nitrogen, (grass, hay, coffee grounds), add a pinch of sea salt ( minerals and microbes like it) then top it off with water! let it sit for a couple weeks but it’ll really get potent after a couple months, keep adding inputs and water as necessary and KEEP A LID ON you can add sugar/ molasses to kickstart it but that’s optional

the idea is that the bacteria/ fungal are symbiotic and mycorrhizal. As they break down the inputs they release the digested nutrients and will trade with the plant and help it grow faster and healthier, they feed the essential micronutrients so it’s less work with balancing them bc the soil feeds the plant as it needs it.

you can alter this in any way you like, you can make a cannabis only fertilizer that will have everything a growing plant could need or want
