Feeding charts: How to use them for cannabis cultivation

Fertilizer charts for growing with marijuana fertilizer are used to know when to use one fertilizer or another. They serve as a guide for growers; however, a common mistake is to use them exactly as written in the chart. It is more advisable to adapt them slightly to your plants rather than doing everything they say. Here, everything you need to know about this is explained.

Factors to consider when using a fertilizer chart

The life cycle of marijuana plants consists of several phases, and each of them has specific nutritional needs. Not all plants follow the same rhythm, and factors such as the type of grow (indoor or outdoor), the environment (temperature, humidity, light), and the genetics will influence the transition times between phases.

Below, we will see how to adapt fertilizer charts based on these factors, ensuring that your plants receive the appropriate amount of nutrients at each stage of their development.

The life cycle of the marijuana plant

The life cycle of a marijuana plant consists of several stages, each of which has specific nutritional requirements. Understanding these changes will allow you to optimize the use of fertilizers and achieve the best results:

1. Germination: The process in which the seed begins to develop.
2. Vegetative growth: The stage where the plant develops, creating branches, leaves, and a strong root system.
3. Pre-flowering: The moment when the first signs of flowering are detected.
4. Flowering: A crucial stage for bud development and resin production.

Each phase presents particular challenges and needs that must be addressed with precision to ensure a healthy and productive plant.

Using fertilizer charts in each phase

Germination: Boosts the plant’s initial development

Germination is the moment the seed begins to open, and the growth of the first roots starts. During this phase, the main goal is to stimulate the growth of the root system, which is essential for nutrient absorption in the following phases.

• Recommendation: Use a root stimulator that favors the formation of strong roots. In this stage, a complete fertilizer is not necessary, just a product that facilitates the start of growth.
• Duration: This process can last between 1 and 7 days, depending on environmental conditions.

Growth: The expansion phase

The growth phase is fundamental for the plant to develop its structure. During this phase, the plant needs fertilizers with a high nitrogen content to promote vegetative growth and the expansion of the root system.

• Key nutrients: Nitrogen (N), Phosphorus (P), and Potassium (K).
• Recommendation: Use an appropriate growth fertilizer and a root stimulator to strengthen the roots. During the second or third week, you can progressively increase the dose of growth fertilizer.

Application example:

• Week 1: Root stimulator to stimulate the roots.
• Week 2: Start with growth fertilizer, increasing doses gradually.
• Week 3-4: Add a fertilizer that favors pre-flowering if signs of change are detected.

Important note: Vegetative growth can vary depending on genetics and environmental conditions, so it is important to observe the rhythm of your plants and adjust the fertilizer chart according to their needs.

Flowering: Maximize bud production

Flowering is the most critical phase for the grower, as it is when the plant begins to develop buds rich in resin. At this stage, it is necessary to adjust the fertilizer regimen to favor flower development.

• Key nutrients: less nitrogen and more phosphorus (P) and potassium (K).
• Recommendation: use flowering fertilizers that stimulate bud fattening. You can add products with carbohydrates and high phosphorus to improve flower formation and resin.

In the flowering stage, specific stimulators can also be added, and you can buy Delta 9 Cannabiogen, especially when looking to reinforce bud fattening and resin production.

Flowering sub-stages:

1. Start of flowering (week 1-3): The first buds begin to form. Use a flowering fertilizer with low nitrogen content.
2. Mid-flowering (week 4-5): The buds begin to fatten. Use products with more phosphorus and potassium to favor fattening.
3. Advanced flowering (week 6 onwards): The plant is at its maximum development. A root flush is recommended to remove nutrient residues before harvest.

Root flush

When the plant barely produces new white hairs and the brown ones start falling off, you should use only water for irrigation until the pot is cleaned, the plant yellows, and no fertilizer residues remain. It is usually done for a week or 10 days, and it is essential so that no residues remain that affect the flavor. To do this, you can apply a product that helps clean, chelating the remaining nutrients, such as Flawless Finish or Final Flush.

If you follow all the steps by phase, paying attention to the marijuana fertilizer charts and the plants to see what phase they are in and what their nutritional needs are. Therefore, you must adapt the chart to them to achieve the best results.
