Hi, noob here. I have some autoflowers in seedling pots (i know its v. late) i need to transplant. Also have some older ones that i bodged a mix for (growing outside). I have
Coco
Worm castings
Fish blood & bone
Epsom salts
Lime
Liquid seaweed extract
Biobizz grow, bloom, topmax, rootjuice
I also have access to a big pile of well composted leaves/grass clippings. The soil here is very alkaline so i don't think i should use it.
Please could anyone tell me a mix of these i can do. Or will it make much difference to get professional soil. This is so confusing!
