When the flowering phase arrives, the nutritional needs of plants change and certain macronutrients become especially important. At this time, having a supplement rich in phosphorus and potassium can help complete your nutrition program.
Big Boom PK 52-34 by Boom Nutrients is a powdered mineral fertilizer with a high concentration of phosphorus and potassium, formulated as a supplement for the flowering phase. Its PK 52-34 composition makes it an especially concentrated option for those looking to boost the supply of these nutrients during flower development.
What is Big Boom PK 52-34?
Big Boom is a highly concentrated mineral fertilizer formulated with a PK 52-34 ratio. Its main function is to complement plant nutrition during flowering, providing phosphorus and potassium in a concentrated amount.
Phosphorus participates in different processes related to energy metabolism and plant development, while potassium is involved in fundamental physiological processes, such as water regulation and various metabolic functions.
Due to its high concentration, Big Boom is used as a supplement to a fertilization program, not as a substitute for a complete base fertilizer.

Big Boom PK 52-34
What is Big Boom used for?
Its main features include:
- High concentration of phosphorus and potassium.
- PK 52-34 formulation.
- Powder format for easy storage.
- Designed to complement nutrition during flowering.
- Can be integrated into different fertilization programs.
- Allows for a high supply of nutrients using small amounts of product.
It is important to remember that a higher concentration does not mean you should use more fertilizer. With concentrated PK products, following the manufacturer’s instructions and monitoring electrical conductivity (EC) is especially important.
Why use a PK during flowering?
During flower formation, the plant continues to need balanced nutrition. Phosphorus and potassium fulfill different and complementary roles within plant physiology.
The role of phosphorus
Phosphorus participates in processes related to energy transfer and storage, as well as in various metabolic processes of the plant.
The role of potassium
Potassium is involved in water regulation, enzymatic activity, and other physiological processes. It is also related to the transport of certain compounds within the plant.
For this reason, concentrated PK fertilizers can be used as a supplement when the nutritional program requires an additional supply of these macronutrients.
Big Boom: a supplement for the flowering phase
One of the main advantages of Big Boom is that it can be incorporated into different fertilization programs, provided there is compatibility between the products used.
The Boom Nutrients range has different products designed to cover the nutritional needs of plants in the various stages of development. Big Boom is especially aimed at supplementing nutrition during the flowering and flower development phase.
Can Big Boom be combined with other fertilizers?
Yes, it can be used within a fertilization program alongside other products, but the composition of all of them must be taken into account.
When combining several fertilizers, it is important to avoid unnecessarily duplicating the supply of phosphorus or potassium and to monitor the EC of the nutrient solution.
The goal is not to add as many products as possible, but to achieve balanced nutrition adapted to the growing medium and the state of the plants.
Big Boom and Candy Boom: two different functions
Within a flowering program, Big Boom can be combined with products that provide other elements to the nutrition.
An example is Candy Boom, a product from Boom Nutrients formulated with vegetable organic matter, plant extracts, sugars, and other components. According to the manufacturer’s information, it is aimed at promoting flower development, aroma, and resin production.
The combination of products should always be done taking into account the corresponding grow chart, the total nutrient concentration, and the actual needs of the plant.
pH and EC control: two fundamental parameters
When working with concentrated fertilizers, controlling the nutrient solution is especially important.
Why monitor EC?
Electrical conductivity (EC) allows you to indirectly know the concentration of dissolved salts in the irrigation water.
When incorporating several fertilizers, measuring the EC helps avoid an excessive concentration of nutrients and allows you to adapt the feeding to the characteristics of the crop.
For those who use concentrated fertilizers frequently, having an EC meter can significantly facilitate the control of the nutrient solution.
And what about pH?
pH is also important because it influences the availability of different nutrients to the roots.
The appropriate range will depend on the growing medium, the water used, and the fertilization program. That is why it is not advisable to establish a single pH value valid for all crops.
In which growing media can Big Boom be used?
Big Boom can be incorporated into different cultivation systems as a nutritional supplement, always respecting the manufacturer’s instructions and the characteristics of the medium.
Soil cultivation
In soil, the fertilizer is integrated into a nutrition program that can include a base fertilizer and different flowering supplements.
Coco cultivation
Coco has different characteristics than soil and requires more precise control of nutrition and EC. In this case, Big Boom should be considered a supplement within a specific program for coco.
Hydroponic cultivation
In hydroponic systems, the control of the nutrient solution becomes even more important, as the roots are directly exposed to the water and the available nutrients.
In all cases, you must check the compatibility of the products before mixing them and avoid preparing excessively concentrated solutions.
Big Boom PK 52-34 formats
Big Boom is available in different sizes to adapt to different cultivation needs.
50 g Big Boom
The small format is practical for those who want to try the product or need a small amount of fertilizer.
250 g Big Boom
The 250 g format is designed for users who need a larger amount and are looking to have enough product for several cultivation cycles.
1 kg Big Boom
The 1 kg format is suitable for those who use Big Boom regularly and need a larger quantity of product.
5 kg Big Boom
The 5 kg format is aimed at users with high fertilizer consumption. In this case, it is especially important to have good nutrition organization and appropriate measuring instruments.
How to incorporate Big Boom into a fertilization program
Big Boom should be understood as a flowering supplement, so its use must be integrated into the general nutritional program.
Before using it, it is advisable to consider:
- The type of growing medium.
- The composition of the base fertilizer.
- The EC of the starting water.
- The final EC of the nutrient solution.
- The development phase of the plants.
- Compatibility with the rest of the products used.
More fertilizer does not always mean better results
One of the most common mistakes when using concentrated fertilizers is thinking that increasing the amount of nutrients will automatically produce better results.
In reality, an excessive concentration can cause nutritional stress, salt accumulation, or absorption problems. That is why it is preferable to work with balanced nutrition and make adjustments progressively.
Is it necessary to flush the roots?
Managing fertilization during the final stages of cultivation depends on the system used, the nutritional program, and the specific recommendations of the fertilizers employed.
There is no universal need to perform an aggressive “root flush” in all crops. The important thing is to avoid an excessive accumulation of nutrients and adjust the feeding according to the medium, the water, and the state of the plants.
If the manufacturer recommends stopping the use of certain fertilizers before harvest, it is advisable to follow the specific product instructions.
