I have a simple system with a pump that adds water to my coco pots once every couple of days but the nutrient solution starts separating (making a foam) after a couple of days.
Do you have solutions for this problem or nutrient suggestions? I am currently using canna coco a/b.
Add an air pump to the reservoir with airstones (like the ones used for aquariums) This will keep the solution aerated and mixed all the time, ready for the next pump.
Hey unfortunately this is just what happens, in fact most nutrient manufacturers will tell you not to mix your nutes more than two days in advance for this very reason.. sorry bro
