i've been top watering grodan cubes in my veg tent since there are plants in various stages of growth before moving them to the hydro flower tent. i would really like to be able to mix a large quantity of nutes at a time, but within a few days they begin to go bad. i've read a little about using sodium benzoate as a preservative, but am not finding enough info to give it a go. does anyone have experience with this? is there another way to preserve my mixed nutes? thank you all!
