Mrs_larimar, this soil amendment is called bokashi. I'm growing organically too, and also prepare my own mix (two different mixtures). But since its my first grow, I think I made the mistake in not filtering the amedment, and just realize that the flushin is not taking away the fine particles that are accumulating at the botton. I think its the reason because the plant with the less % of bokashi is showing a lower runoff EC than other with higher % of bokashi. Since I dont have the opportunity to buy a formal flush solutions suggested by the other growmies, I think I have to finish the flushing period as normally and chop the babies.
