Micronutrient & macronutrient deficiencies and their symptoms

The list below shows the nutrients most plants need and their symptoms if the nutrient is deficient.

Micronutrients- Cofactors that aid essential cell mechanisms that are

needed in small amounts.

• Boron - terminal growths die/thickened/curled/wilting/reduced flowering
• Chlorine - wilting/yellow-green/leaf bronzing; poor growth/marginal leaf necrosis
• Copper - stunted growth/leaf tips die; reduced growth
• Iron - yellow-green/reduced growth; low stunted growth/purple/poor fruit development
• Manganese - yellow-green of leaves/similar to iron; low stunted growth/purple/poor fruit development
• Molybdenum - stunted/reduced yield/cupping/rolling
• Zinc - leaf tip necrosis; interveinal yellow foliage/induces iron and zinc 

Macronutrients- Involved in photosynthesis and protein synthesis that are used heavily and need to be replaced.

• Nitrogen - slow stunted growth/yellow-brown; heavy growth/dark green/delayed maturity/low fruit yield
• Phosphorus - slow stunted growth/purple/poor fruit development; yellow-green/short stems
• Potassium - slow growth/weak stalks/small fruit; light green
• Calcium - shortened growth of shoots; E: interferes with micronutrients
• Magnesium - curled up leaves/yellowing in christmas tree pattern; interferes with Calcium uptake
• Sulfur - reduced growth/delayed maturity/light green-yellow
