With the 1:1:1, its referring to peat:compost:aeration. So say your recipe was gonna be 2 gallons peat, 2 gallons compost ( or castings, or both!), 2 gallons perlite, I would advise using 1 gallon of FFOF and 1 gallon of peat in that aspect of the ratio. Your compost is the life of your soil so I always advise it to be the biggest investment in time and money. Nutrient teas as you're going to find on most forums are bullshit, the only way to create a 'nutrient' tea is through fermentation and creating a Fermented Plant Extract (FPE), youtube is full of tutorials for creating FPE's and harvesting the bacteria needed to create it. For now though, lets just get this soil mixed up properly, we can get to that stuff when its needed. You will need to let your soil set for at least a month, I personally give it 2 months, constantly wetting with various microbes to keep everything active. You're no bother man, ask away
