I made a 4000 ppm N solution by dissolving 30 g K-Lite in 1 L RO water. I've been keeping it on the countertop in the kitchen, out of sunlight but not refrigerated. After two weeks, I have 2/3 of the bottle left, but now there are cloudy billows floating on the bottom of the bottle. I realize it's bacteria, but is the concentrate still ok to use? Or are the critters devouring all the nitrogen?
If I need to throw it out, should I keep the concentrate in the fridge from now on?
