Based on Rickster's suggestion, I decided to compile a brief list of Elements commonly discussed in Planted Aquaria. Feel free to add any elements I might have missed, but post specific questions in a new topic. Discussions should only relate specifically to the Scientific Notations.
- N: Nitrogen, a core building block for plant growth. Macronutrient.
- P: Phosphorus, a core building block for plant growth. Macronutrient.
- K: Potassium, a core building block for plant growth. Macronutrient.
- NO3+: Nitrate, a common form of nitrogen available in an aquarium as a result of nitrifying bacteria breaking down ammonia.
- NH3+: Ammonia, a basic form of nitrogen available in an aquarium, formed by fish waste.
- NH4+: Ammonium
- NO2: Nitrite, the second state of nitrogen in the biological cycle in an aquarium.
- KNO3: Potassium Nitrate. Stump Remover. Readily available form of Potassium and Nitrate in salt form.
- K2SO4: Potassium Sulfate. Good source of potassium for plant growth.
- KCl: Potassium Chloride. Saltpeter. Potash. Good source of potassium for plant growth.
- MgSO4: Magnesium Sulfate. Epsom Salts. Good source of magnesium for plant growth. Macronutrient.
- KH2PO4: Potassium Phosphate (monobasic). Good source of Phosphate for plant growth.
- CO2: Carbon Dioxide, an easily dissolved gas that is a basic building block for plant growth.
- O2: Oxygen gas.
- pH: Power of Hydrogen. Measure of acidity/alkalinity.
- KH: Carbonate Hardness.
- GH: General Hardness (mostly representing Magnesium and Calcium salts).
- TDS: Total Dissolved Solids
- DOC: Dissolved Organic Compounds
- DIC: Dissolved Inorganic Compounds
- Mg: Magnesium. Macronutrient.
- Ca: Calcium. Macronutrient.
- H: Hydrogen. Macronutrient.
- O: Oxygen. Macronutrient.
- S: Sulfur. Macronutrient.
- Fe: Iron. Micronutrient.
- Zn: Zinc. Micronutrient.
- Ni: Nickel. Micronutrient.
- Cl: Chloride. Micronutrient.
- Cu: Copper. Micronutrient.
- B: Boron. Micronutrient.
- Mn: Manganese. Micronutrient.
- Mo: Molybdenium. Micronutrient.
We'll add to the list as the thread progresses.

This is a guide for dosing of several of the more popular elements dosed in a planted tank.
