Which soil recipe of BAS did you buy? I think I get my best results from soil I make myself. There’s a worm farm nearby I buy casting from and it works excellent when I don’t have enough of my own to use. I bought Roots Organic Greenfield bagged soil and added some ewc, kelp and crab meal lightly for bloom and it’s been surprisingly growing plants in veg just with added ewc just as good as my homemade soil with just water.
