I have day old nutrient water that was left over from the past days feeding, its been left out without a lid and now the water is visibly cloudy. I'm guessing its from bacteria and such blooming in the water, I plan on dumping it, but out of curiosity would it be harmful to my plants? The nutrients used (2 drops in 16oz water) were FF grow big. Thanks!
My nute water is typically cloudy and or blackish in color when I use molasses. I would not worry about it.
