The Pro XL feeding chart

In the world of cannabis cultivation, nutrition is one of the most critical aspects of achieving high-quality harvests. Choosing the right products can mean the difference between a mediocre and an exceptional grow. For growers seeking consistent and controlled results, the Pro XL feeding chart has become an indispensable tool. Learn how to use it in this article.

What is Pro XL?

Pro XL is a brand of organic mineral fertilizers designed to provide plants with everything they need. It functions as a specialized nutrient line tailored to each phase of the plant’s lifecycle, with additives and products for flower development. Its ultra-concentrated doses allow growers to use smaller amounts while achieving lower EC levels, making it cost-efficient and effective.

The Pro XL feeding chart is a nutrition and cultivation planning system specifically designed to optimize cannabis growth and production. Developed by experts in the cultivation industry, the Pro XL chart is a detailed guide that helps growers efficiently manage their plants’ nutrient cycles.

Why use Pro XL?

Using the Pro XL chart offers numerous advantages for cannabis growers, both in terms of results and cultivation efficiency. Here are some reasons to consider Pro XL:

• Optimized growth and flowering: The Pro XL chart covers all cultivation phases, from germination to flowering. It promotes healthy growth during early stages and enhances bud production during flowering, maximizing yield and quality.
• Ease of use and planning: This comprehensive tool guides growers through the entire cultivation cycle. It enables precise nutrient scheduling, avoiding deficiencies or overdoses while facilitating smooth transitions between phases.
• Better nutrient management: Pro XL helps prevent nutritional imbalances by ensuring plants receive exact amounts of nutrients. This avoids deficiencies or toxicities that could harm the plant’s performance.
• Consistent and predictable results: Following a detailed nutrition plan allows growers to achieve consistent, high-quality results, improving harvests over time through precise control of cultivation conditions.
• Cannabis-specific formulas: Pro XL products are tailored to meet cannabis needs, ensuring better plant health and resulting in higher-quality yields.

Products in the Pro XL chart

The Pro XL chart includes a comprehensive range of products designed for the various stages of the cannabis lifecycle. Each product is crafted to supply the specific nutrients that plants need during each phase. Below are some key products in the system:

Base fertilizers

Base fertilizers are essential for providing plants with the fundamental nutrients they need for development.

• Grow A+B: Used during the vegetative stage, promoting healthy and robust growth.
• Bloom A+B: Designed for the flowering stage, helping to maximize flower and bud production.

Flowering boosters

To enhance bud production, the Pro XL system includes specific boosters like Pro XL Bloom XXL and Pro XL PK+. These products intensify flowering, increasing both the quantity and density of buds for a more abundant and higher-quality harvest.

End-of-cultivation formulas

At the end of the cultivation cycle, root flushing is essential to remove excess nutrients and prevent residues from affecting the final product’s taste and aroma. Pro XL Clean is formulated for this purpose, ensuring a clean and flavorful harvest.

Micronutrients and additional supplements

In addition to primary fertilizers, the Pro XL chart includes micronutrients and supplements that provide essential elements like calcium, magnesium, iron, and other minerals that may be missing from soil or irrigation water.

How to use the Pro XL feeding charts

The Pro XL chart not only provides nutrients but also a structured irrigation and fertilization schedule, making it easier for growers—even beginners—to manage their crops. While simple to use, attention to detail is crucial to achieve the best results. Follow this basic guide to use the chart effectively:

Read the instructions for each product

Each Pro XL product comes with a specific dosage guide. It’s vital to follow the manufacturer’s recommendations to avoid over-fertilization or deficiencies. Dosages vary based on the growth stage and plant size.

Follow the irrigation and fertilization schedule

The Pro XL chart includes a calendar indicating when to apply each product during the cultivation cycle. Ensure you respect intervals between applications and adjust water and fertilizer amounts according to your cultivation conditions (temperature, humidity, and grow medium type).

Monitor pH and EC levels

Check the pH and EC of the nutrient solution before watering. The pH should be within an optimal range (usually 5.8–6.5 for hydroponics and 6.0–6.5 for soil) to ensure plants can efficiently absorb nutrients.

Adjust during flowering

During the flowering phase, nutrients need to change. The Pro XL chart provides precise dosages, but adjustments may be necessary depending on how your plants respond. Some may require more or less fertilizer during the final weeks.

Observe your plants

While the Pro XL chart is a comprehensive guide, observing your plants is always crucial. Adjust the plan if you notice signs of deficiencies or excess nutrients.

Pro XL feeding charts

Pro XL feeding chart for coco and hydroponic grows

The Pro XL chart is perfect for cultivation in coco substrates or hydroponic systems. These mediums typically contain fewer nutrients than pre-fertilized soil, requiring higher fertilizer doses. While the same Pro XL products are used, dosages are adjusted to meet the specific needs of these nutrient-deficient substrates.

Pro XL chart for pre-fertilized substrates

The Pro XL feeding chart is also suitable for cultivation in pre-fertilized substrates like peat or soils with added nutrients. In this case, Pro XL product dosages are reduced to avoid nutrient excesses since these substrates already provide a base level of nutrition. The amounts are lower compared to coco or hydroponic grows, ensuring balanced growth without overuse.

The Pro XL feeding chart is an invaluable tool for growers looking to optimize cannabis cultivation. With high-quality products specifically formulated for cannabis needs, this chart offers a comprehensive solution for maximizing yield and harvest quality.
