Creating a Flowering Soil Mix for Your Cannabis Plants

A flowering soil mix is designed for plants or clones that are entering the flowering stage. This mix has enough nitrogen to support a couple of weeks of vegetative growth and the stretch phase. However, growers may need to supplement nitrogen if they notice yellowing leaves before five weeks into the flowering stage. This article will provide a basic mix recipe and tips for managing nutrients in your flowering soil mix.

Flowering Soil Mix Recipe

The basic mix consists of:

  • 40% castings
  • 30% perlite
  • 30% vermiculite
For each gallon of soil mix, add:

  • 1/4 cup of high N guano
  • 1/2 cup of high P guano
  • 1/4 cup of dolomite lime
  • 1/4 cup of kelp meal
Managing Nitrogen and Phosphorous in Your Soil Mix

The high nitrogen guano can be variable, and different sources may break down differently, potentially burning your plants. However, high N guano breaks down quickly and is used by the plant immediately. Growers can monitor for burned tips or ram's horn leaf curl to determine if their plants are receiving too much nitrogen.

On the other hand, high phosphorous guano breaks down slowly and needs to be supplemented early with an organic flowering fertilizer, such as EarthJuice bloom.

Watering and Feeding Your Plants

When potting your plants, water them with a mix containing 1 tbsp each of EarthJuice Catalyst and Maxicrop Liquid Seaweed per gallon of water. If using B'cuzz, add it as well. Afterward, use the EarthJuice/Maxicrop mix every third watering. Make sure to feed your plants with a bloom fertilizer until the fourth week of flowering.

Conclusion

Creating a proper flowering soil mix is essential for the successful growth and flowering of your plants. By following this recipe and closely monitoring the nitrogen and phosphorous levels in your soil, you can ensure your plants receive the nutrients they need without risking damage. Remember to water and feed your plants consistently with the appropriate nutrient mix to support their growth and flowering needs.
