  • Yellowing at the tips and edges, usually in younger leaves
  • Dead or yellow patches develop on leaves
• Phosphate


  • Leaves are darker than normal
  • Loss of leaves
• CARBON DIOXIDE 


  white deposit ls on leaves, stunted growth and plants die back
• MACRONUTRIENTS 


  refer to the materials needed by plants in larger amounts
• MICRONUTRIENTS 


  materials needed by the plants in small amounts

  •PHOSPHORUS (roots and blooms)

  •POTASSIUM (plant gtowth)
• OTHER MACRONUTRIENTS

  hydrogen & oxygen, carbon, sulfur, calcium, and magnesium
• HYDROGEN AND OXYGEN  

  for photosynthesis and cellular respiration. form of water and oxygen gas
• CARBON


  form carbohydrates, proteins, nucleic acids, and other relevant compounds
• SULFUR


  macromolecule since it is a common component of some amino acids like cysteine and methionine
• CALCIUM 


  regulates nutritent transport and supports enzyme functions
• MAGNESIUM 


  maintaining plants ionic balance
• MICRONUTRIENTS THINGS
