Hey. I'm thinking of grow some plants with a slow release fertilizer. Use only powders. Growing in coco & perlite indoor , Organic . with some mycorrhiza. I saw someone grow up like this on the net and I can not find the fertilizer he uses in my country so I'm looking for something similar for veg- balanced fertilizer 4-4-4 (1-1-1 ratio ). for bloom 2-8-4 . Can anyone recommend me this type of fertilizer? What else should I know?
