🔍 Possible Causes (2)
Nutrient Deficiency
Nutrient deficiency occurs when a plant cannot access one or more essential mineral elements in sufficient quantities for healthy growth. Plants require 17 essential nutrients: macronutrients (N, P, K, Ca, Mg, S) and micronutrients (Fe, Zn, Mn, Cu, B, Mo, Cl). Each plays a unique role in metabolism, structure, and reproduction. Deficiencies arise from depleted soils, incorrect pH blocking uptake, poor watering practices leaching nutrients, root damage, or imbalanced fertilization. Understanding whether a nutrient is mobile or immobile determines where symptoms first appear: mobile nutrients (N, P, K, Mg) show symptoms on older leaves first, while immobile nutrients (Ca, Fe, Zn, Cu, B) show symptoms on new growth first.
✓ Related symptoms:
- • Nitrogen (N): overall yellowing starting from older/lower leaves, progressing upward; slow stunted growth; pale lime-green foliage
- • Magnesium (Mg): interveinal chlorosis on older leaves (veins stay green while tissue yellows); leaves may curl upward; premature leaf drop
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
