Default Marijuana Plant Problems and Cures
Before we get into this I want you to check a couple things, check the following things:
  • Plants have plenty of water
  • Soil is seven PH or even a little less
  • Your light cycles are correct
  • No pools of water
  • Constant fresh air
Now thats out of the way let Mr. Ganja God diagnose your plant

Bigger leaves are turning a yellowish color while the smaller leaves are green.
  • Nitrogen deficiency - add nitrate of soda or organic fertilizer.
Older leaves will curl at edges, turn dark, possibly with a purple cast.
  • Phosphorous deficiency - add commercial phosphate.
Mature leaves develop a yellowish cast to least veinal areas.
  • Magnesium deficiency - add commercial fertilizer with a magnesium content.
Mature leaves turn yellow and then become spotted with edge areas
turning dark gray.
  • Potassium deficiency - add muriate of potash.
Cracked stems, no healthy support tissue.
  • Boron deficiency -add any plant food containing boron.
Small wrinkled leaves with yellowish vein systems.
  • Zinc deficiency - add commercial plant food containing zinc.
Young leaves become deformed, possibly yellowing.
  • Molybedum deficiency - use any plant food with a bit of molybdenum in it.
