Great thing is about fermented tea brews is the relationship between the bacteria, fungi and nutritional uptake of the plant. It's very rare to overdose on a strong brew, plant intelligence becomes the doseatron meter and the plant will only uptake what it needs since the brew is 100% plant based and without synthetics the soil will just store the excess nutrients and the plant can ask for it later. With the research I've done while creating a system for large scale feeding with ferments, i let the brew do its thing for 1 week and dilute 1:50 - Brew:6.4 pH Water. Week 2 the ratio becomes 1:75. Week 3 the ratio is 1:100. The dilution rates are so high because I apply 3x a week: once as a foliar, two as soil drenches. The dilution rates are also based from a brew starting off with 55gallons of harvested plants, 1 gallon of lactic acid bacteria and 1 quart of kimichi juice. The bacteria breaks the plant material down so fast that by the end of week 3, it's pure liquid, perhaps only a hand full of what once was woody material left that is on it's way to be completely dissinegrated.
