🔍 Possible Causes (5)
Transplant Shock
Transplant shock is a stress response that occurs when plants are abruptly moved from one environment to another. This environmental condition affects plants during repotting, moving between indoor/outdoor locations, or transplanting from nursery pots to gardens. Root damage during the move is the primary cause, making it nearly impossible to completely avoid some degree of stress.

Soil pH Imbalance
Soil pH imbalance occurs when soil becomes too acidic (low pH < 6.0) or too alkaline (high pH > 7.5), preventing plants from absorbing essential nutrients. The ideal pH range for most plants is 6.5-7.5. When pH is outside this range, nutrients become chemically locked in the soil, leading to deficiency symptoms even when nutrients are present.

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
Leaf Spot
Leaf spot is a common fungal disease caused by various pathogens including Alternaria, Ascochyta, Colletotrichum, Septoria, and Venturia. It primarily affects leaves, causing discolored spots that can lead to premature leaf drop if left untreated.
✓ Related symptoms:
- • Circular brown, gray, black, or yellow spots on leaves
- • Yellow halo surrounding spots
⚡ Quick Fixes:
Remove all visibly infected leaves
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.
