Role: Vital for vegetative growth. It is a key component of chlorophyll, which is necessary for photosynthesis.

Symptoms of Deficiency: Yellowing of older leaves, stunted growth, and weak stems.

Role: Essential for energy transfer and root development. It aids in the formation of DNA and RNA, and is crucial for flowering and fruiting stages.

Symptoms of Deficiency: Dark green or purple leaves, poor root development, and reduced flowering.

Role: Important for overall plant health, including water regulation, enzyme activation, and the synthesis of proteins and carbohydrates. It enhances disease resistance and helps in the development of strong stems and buds.

Symptoms of Deficiency: Marginal chlorosis (yellowing) on older leaves, weak stems, and reduced bud development.

Calcium (Ca):

Role: Crucial for cell wall structure and stability. It also plays a role in nutrient uptake and enzyme function.

Symptoms of Deficiency: Young leaves may show curling or distortion, and the plant can become more susceptible to diseases.

Magnesium (Mg):

Role: Central component of the chlorophyll molecule, aiding in photosynthesis. It also helps in the activation of enzymes and the synthesis of proteins.

Symptoms of Deficiency: Interveinal chlorosis (yellowing between the veins) on older leaves, starting from the bottom of the plant.

Sulfur (S):

Role: Important for the synthesis of amino acids, proteins, and enzymes. It also contributes to the formation of chlorophyll.

Symptoms of Deficiency: Yellowing of young leaves, stunted growth, and poor flower development.
