Marijuana Fertilization Tips

To grow to a large size, marijuana requires a steady supply of nutrients which should be added to the water on a regular basis. The following is a list of tips for fertilizing marijuana to ensure huge growth for your plants.

 

  • The elements Nitrogen, Phosphorus, and Potassium are considered the important nutrients for strong growth.
  • Calcium can be used to control the pH.
  • Adding ample Nitrogen ensures fast lush growth, enabling a Cannabis plant to outgrow almost any other plant.
  • Cannabis’ need for phosphorus is the greatest during the seedling and flowering stages of it’s life cycle.
  • Potassium is associated with strong sturdy stems and plants with a high resistance to diseases and pests.
  • Calcium is not added to the soil as a nutrient, but rather to balance the pH of the soil.
  • The amount of nutrients to add to the water depends on the size of the plant, the size of the pot, and the general condition of the soil.
  • Always add water when you add any nutrients or fertilizer to the soil.
  • It is recommended that you dissolve the fertilizer in the water before watering the plant.
  • Adding more nutrients than a plant requires will toxify the soil thereby harming plant growth and development.
  • Foliar feeding, or spraying the leaves with a fertilizer solution, is an ideal way of fertilizing large plants with nutrient deficiencies.
  • Nutrient deficiencies can best be detected by a change in the condition and color of the leaves.
  • Soil-less mixtures are a good alternative to using large amounts of soil, the main advantage being that the nutrient balance is easy to control.
  • The pH is the measure of how alkaline or acidic the soil is and it’s balance is determined by the amount of nutrients present in the soil.
  • Although marijuana will grow in soils with a pH between five and nine, it thrives in soils with a neutral pH of around seven.
  • Soils with a high content of organic matter are often quite acidic with a fairly low pH.
  • Calcium can be used to balance the pH.
  • Most nutrients are soluble in soils with a pH balance of between six and seven and a half.
  • Continued use of Nitrogen, Phosphorus and Potassium will lower the pH of the soil, this can be rectified by adding some Calcium.
  • To save over-fertilized plants, the soil can be leached by removing the top few centimeters and over-watering with lukewarm water.
  • Although healthy, strong growing plants love a steady supply of nutrients, you should never fertilize them every day.
  • A plant growing in a poor soil, low in nutrients will develop better than a plant growing in over-fertilized soil.
  • Although Carbon Dioxide cannot be classified as a true nutrient, it can been used to increase growth during the vegetative stage.
  • To balance the pH of an acidic soil, crush some egg-shells and soak them in water. Then strain out the shells and pour the water over your plants.
  • A soil rich in Nitrogen will increase internodal growth in the stems of developing young marijuana plants.
  • Urine is an excellent source of Nitrogen for marijuana plants, but as it is too concentrated to apply directly, it should always be diluted with water.
  • Unless the soil is poor in nutrients, a young seedling growing in a large pot doesn’t require any fertilizing for the first few weeks of it’s life.
  • Although Cannabis does not grow well in a soil with a low nutrient content, this is preferable to a soil that has been toxified by over-fertilization.
  • The influence of the soil, and in particular the nutrient content of the soil, to the potency of the plant is something which cannot be overlooked.
  • Nitrogen can be positively correlated with higher potency and increased growth, and it is the most influential nutrient available to the grower.
  • Organic fertilizers are less concentrated than chemical mixes, and as the nutrients are released more slowly, there is less chance of toxifying the soil.
  • A typical program of fertilization may be to fertilize after the fifth week of growth, and then every two weeks thereafter until flowering.
  • It is always better to fertilize your plants more often with a more diluted solution, than to give them concentrated doses at longer intervals.
  • Always make sure that the fertilizer is completely dissolved in the water before you apply it to your plants.

  1. can you use fertilizer for blooming flowers for blooming cannibus or does it have to be a fert. for veggies for cannibus thank you

  2. if you think your plants are approaching that stage , bloom booster products work very well.

  3. Schultz bloom plus or bloom booster by commercial companies that high phosphate ratios work great but should be used sparingly and used diiluted
