Nutrient Deficiency

Plants need various macro and micronutrients. Deficiency symptoms vary by nutrient but generally show as discoloration, poor growth, or abnormal leaf development.

가능한 원인

Nitrogen Deficiency

Why: Nitrogen is essential for chlorophyll and overall growth. It is mobile in the plant, so deficiency shows on older leaves first.

Signs to check: Older/lower leaves turn uniformly pale yellow-green, growth is slow, plant looks sparse.

Iron Deficiency

Why: Iron is needed for chlorophyll synthesis. It is immobile, so new leaves are affected first.

Signs to check: New leaves are yellow with green veins (interveinal chlorosis), older leaves remain normal.

Potassium Deficiency

Why: Potassium regulates water movement and enzyme function. Deficiency weakens the plant.

Signs to check: Leaf edges turn brown and scorched-looking, older leaves affected first, weak stems.

Depleted Potting Mix

Why: Nutrients in potting soil are consumed or leached out over time, especially with frequent watering.

Signs to check: Plant has not been repotted or fertilized in over a year, multiple deficiency symptoms.

확인 사항

1
Note which leaves are affected — older (lower) or newer (upper)?
2
Describe the pattern — uniform yellowing, interveinal, or edge browning?
3
Check when the plant was last fertilized or repotted
4
Consider whether overwatering has leached nutrients from the soil
5
Assess overall growth rate compared to what is expected for the species

다음 단계

Apply a balanced liquid fertilizer (e.g., 10-10-10) at half strength
For iron deficiency specifically, use a chelated iron supplement
Repot in fresh, quality potting mix to replenish soil nutrients
Establish a regular fertilizing schedule during the growing season
Avoid over-fertilizing — more is not better and can cause burn

도움을 구할 때

Deficiency symptoms are worsening despite fertilizing (may be a pH or root issue)
Leaf tips and edges are burning after fertilizing (too much, too strong)
Plant shows multiple severe deficiency symptoms simultaneously

핵심 포인트

Which leaves are affected tells you which nutrient is lacking. Older leaves point to mobile nutrients like nitrogen; new leaves point to immobile nutrients like iron.
