Potassium Deficiency in Plants
Potassium Deficiency in Plants Notes:
Potassium (K) is a macronutrient.
- Yellowing between veins of leaf (Interveinal chlorisis). Reduced flowering/fruiting. Leaf tips can look burnt or black.
- Potassium carbonate or potassium hydroxide (pearl ash, potash).
- This will raise PH, so add Potassium slowly and test every few days.
- Heavy metals added to a closed loop system will ruin an aquaponics system.
