So recently I've gone dry amendments so what I do is reuse my soil from last grows and add perlite as well as coco then worm castings and bone meal as well as blood meal and also use a seedling fertalizer with everything in it as well for about I'm guessing 5weeks it should last then I start using a higher nitrogen liquid fertalizer if I veg for longer or I transplant and add a bone meal and castings mix in that soil with the seedling fertalizer which is more or less 1.1.1.1 mg is higher and calmag higher not sure off top of my head but its a lite mix so then I use a canna pk with that for flower as well after 4weeks which seems to be OK but I'm thinking of throwing in a base as well for flower hoping to give it abit more boost but not sure how they going to handle it yet what do uz think
