I usually brew two or 3 throughout the flower cycle and once a month in veg. I take some RO water and add fish hydrolosate, a little molasses and some of that “fish sh!t” (only because I have a ton of sample bottles from the grow shop). I then take a handful of fresh casting and mix those with a some high p guano, kelp meal, alfalfa meal and sometimes some rock dust. Throw it in a reusable coffee filter and bubble it with an air stone for a day and a bit. It should lose the molasses smell after about a day and just smell like a fresh worm bin. The plants love it.
Here’s one that’s brewing right now
