If you’ve been trying to read your plants to determine what kind of nutrients your plants need, Aquatic Plant Central member Zapins has put together a diagram that will make leaf divining that much easier. There is a small suite of nutrients that are crucial to sustained plant health and when a deficiency manifests itself, the appearance of aquatic plant leaves will reflect what kind of nutrient(s) is lacking. Senior APC member has taken the time to sketch out a very detailed, easy to follow diagram which will make it that much easier to get the hang of dosing your planted aquarium. Big thanks to Zapins for making this diagram available. The original APC thread can be seen here, follow the break for the full plant deficiency diagram.
