As you may know I just started growing plants (another just sprouted today!!). I have "Plant Gro" the directions say to add 1 capful per 10gal. Ok, but how often? Do I have to test the water and only add it when the iron levels are low or can I safely add a cap every day/other day/week/month, etc?? Any info is appreciated, thanks.
