You can find several recipes online and on youtube. The are all pretty similar to this:

What I do is add a double dose of microbes to 5 gals dechlorinated water. I also add 2 tbs of molasses, 2 tbs of fish emulsion, 1/4 cup worm castings, and 1 tbs of Bio-weed. I used to add a dose of humic acid when I had it around. Another great thing you can do is throw in a handful of activated compost. Make sure that the water temp is between 75 and 85 degrees and aerate it for at least 24 hours. After you've aerated it for this period of time add some surfactant to it. I store mine in old milk jugs in the fridge. Don't let it stay in there too long cuz it will die, supposedly. This tea is especially good in the vegetative stage.
Now that I think about it... you're growing in soil, right?
