Nitrogen
Function: Synthesis of amino acids and proteins; Deficiency Symptoms: Yellowing of leaves (chlorosis), stunted growth
Phosphorus
Function: Energy transfer (ATP), root and flower development; Deficiency Symptoms: Dark green or purple leaves, delayed maturity
Potassium
Function: Regulates osmotic balance, activates enzymes; Deficiency Symptoms: Browning of leaf edges, poor resistance to pests and diseases
Calcium
Function: Structural component of cell walls, cell division; Deficiency Symptoms: Blossom end rot in fruits, stunted root growth
Magnesium
Function: Central atom in chlorophyll molecule, enzyme activation; Deficiency Symptoms: Interveinal chlorosis, leaf curling
Sulfur
Function: Constituent of several amino acids, vitamins and enzymes; Deficiency Symptoms: Uniform yellowing of leaves, delayed maturity
Iron
Function: Chlorophyll synthesis, electron transport in photosynthesis; Deficiency Symptoms: Interveinal chlorosis in young leaves, stunted growth
Manganese
Function: Activating certain enzymes, synthesis of chlorophyll; Deficiency Symptoms: Interveinal chlorosis, brown spots on leaves
Zinc
Function: Hormone production, internode elongation; Deficiency Symptoms: Shortened internodes (rosetting), leaf discoloration
Copper
Function: Important for photosynthesis and respiration, lignin synthesis; Deficiency Symptoms: Wilting of leaves, dieback of shoot tips
Boron
Function: Cell wall formation, sugar transport; Deficiency Symptoms: Terminal bud dieback, cracked stems
Molybdenum
Function: Nitrate reduction, nitrogen fixation; Deficiency Symptoms: Mottled or pale leaves, stunting of entire plant
Chlorine
Function: Osmoregulation, stomatal function; Deficiency Symptoms: Wilted chlorotic leaves, stunted root system
