I belive that you want to use worm castings, along with bat quano in order to create a tea that you THEN add to your resevoir. You would want to create the water/castings/molasses in a container of water, then add beneficial fungi (if you can) and aerate it with an airstone for 24 hours or so. This allows the beneficial microbes to grow rapidly. You will want to mix an amount into your resevoir, then check your PPM and PH. make sure it doesn't throw it too far out of whack. Add small amounts at a time untill you get proper quality.
Strain off everything very well, or you will get sludge and smelly nasty bad fungi/bacteria. Your plants can't even absorb most of that stuff right off the bat. Adding a tea is old school for soil growing, hydroponics is different, we have to make sure everything is readily available for the plants roots to absorb, and is clean to beat away unwanted fungi and such. If there is any additives other than that in the mix, it needs to be beneficial fungi and the stuff they can use to thrive.
