5oz is way way way to much man. For a tea in a 5gal bucket with 2-3 gal water.I'll throw about 1 to 2 tablespoons of recharge . A handful of wormcastings(ancient forest is what
I use ) add 30 mil molasses and a few air stones 1 or 2 is all you need. For the worm castings put them in a tied up sock or panty house works the best. Otherwise you have to strain the shit out. If you want to get fancy you can use pretty much any of the name brand bennies. Great white ,voodoo juice, hydrogurad , zho and countless others. They all have the plus and minus but to each is own. Brew for 48 hrs after that add 1 cup per gal of your rez. Take the remaining tea put in a jug in the fridge will last 7 + days just smell it. If it smells like asshole it's bad should have a earthy smell. Add again 3-4 days later. This will be your best weapon against rootrot. Allowing you to get slightly higher water temps. Also the more diverse the tea you make will also help act as a buffer. Allowing a slightly larger ph swing. The fungi mycroizel and bacteria help the plant uptake nute also eating away at dead material. I tryed sterile rez for years started with teas won't look back turned off my chiller and couldn't be happier.
