I just use extract as there’s things that can go wrong with tea. I’ll add some blackstrap molasses, powdered milk sometimes because it’s the only milk readily available raw milk isn’t really an option. In 1000l I’ll use probably 60lbs of compost but I make it in roughly 375l batches. More during the spring/growing season I’ll add bone meal that’s been extracted with vinegar for a liquid phosphorus/micronutrient extract.
