MisterIto's beginner nutrient flushing formula

In hydroponic systems, managing the nutrient levels is crucial for optimal plant growth and ensuring the final product has the best taste, aroma, and burn. This article will discuss the importance of keeping leaves green until week 5 or 6, metabolizing remaining minerals, and maintaining proper total dissolved solids (TDS) in the final flushing solution. Additionally, we will provide a recommended nutrient solution for enhancing plant growth.

The Importance of Green Leaves Until Week 5 or 6​

Leaving as many leaves green on the plant until week 5 or 6 allows the plant to maximize its photosynthesis capabilities. Photosynthesis is essential for the plant to produce energy, and green leaves are the primary sites for this process. By keeping the leaves green during this period, you enable the plant to efficiently produce food and grow, which ultimately results in a better final product.

Metabolizing Remaining Minerals in the Final Weeks​

During the last 2 or 3 weeks of growth, it's essential to metabolize the remaining minerals present in the plant. This ensures that the plant utilizes all available nutrients, which contributes to better taste, aroma, and burn when the final product is consumed. Proper flushing and nutrient management during this period can significantly impact the quality of the final product.

Maintaining Proper Total Dissolved Solids (TDS) in the Flushing Solution​

The TDS in the final flushing solution should be between 400-500ppm. In hydroponic systems, it's crucial not to reduce the solution ppm much lower, as it will shock the plants by causing reverse osmotic pressure on the roots. This may lead to reduced nutrient uptake, affecting plant growth and final product quality. Maintaining proper TDS levels ensures that the plants have access to the necessary nutrients without causing stress.

Here is a suggested nutrient solution to enhance plant growth in hydroponic systems:

  1. Botanicare Pure Blend Pro Bloom: 5ml/gal
  2. Dyna Pro-Tekt: 1ml/gal, used as pH up and silicon source
  3. FoxFarm Big Bloom: 15ml/gal
  4. 3% hydrogen peroxide: 30ml/gal, every other day
This nutrient solution provides the necessary nutrients for optimal plant growth while ensuring the pH levels and silicon content are maintained. The addition of hydrogen peroxide helps oxygenate the roots, promoting better nutrient uptake and overall plant health.


Proper nutrient management is essential for enhancing plant growth and quality in hydroponic systems. By keeping leaves green until week 5 or 6, metabolizing remaining minerals during the final weeks, and maintaining proper TDS levels in the flushing solution, you can ensure the final product has the best taste, aroma, and burn. Using the recommended nutrient solution will provide the necessary nutrients for optimal plant growth and result in a higher quality final product.
