2. FoxFarm Liquid Nutrient Trio

This three-part combination features FoxFarm’s best-selling liquid nutrient solutions. The set includes the famous Big Bloom, Tiger Bloom, and Grow Big fertilizers. Each has specific functions, but all work hand-in-hand to achieve healthier blooms.

For a start, use the Grow Big liquid plant food to grow abundant and intense-colored blossoms. Its application should begin within two weeks after transplantation of the crop.

Then, as soon as you see signs of initial bud growth or flowering, switch on to using the Tiger Bloom plant food. This is a very potent and fast-acting solution. It has high levels of phosphorus, fair amounts of nitrogen, and plenty of trace minerals. All these nutrients promote the bountiful production of flowers, fruits, and buds.

To extend the flowering and fruiting stages of the plant, you can then add Big Bloom plant food later in the season. This solution is being made with 100% organic fertilizers, including earthworm castings and bat guano. 

Sounds yucky? Not really!

Cultivars seem to love this kind of stuff. It makes them develop bigger blooms, tastier fruits, and thicker seed pods. Now, isn’t that a sweet treat?

Furthermore, you can also continue to use the Big Bloom solution for the entire growth cycle. This fertilizer aids in the healing of the plant’s root systems. It can help promote nutrient cycling too. This process is vital in the ecosystem as it provides organisms the nutrients it needs to flourish as well.

Things to concern:

While Big Bloom is a 100% organic fertilizer, the Grow Big and Tiger Bloom aren’t. These two solutions contain synthetic nitrates and phosphates. So if this concerns you, then buying the entire set may not be your best choice.

Magic Line:

A detailed and target-specific blooming fertilizer

 Features:

• Grow Big NPK ratio: 6:4:4
• Tiger Bloom NPK ratio: 2:8:4

This bloom booster is one of Miracle-Gro’s popular range of fertilizers. The main target of this plant food is to promote abundant blooms with vibrant color features. This unique formulation is suitable to use on all kinds of blooming plants.

Miracle-Gro Bloom Booster contains high levels of phosphorus. This macronutrient is vital for the normal growth and development of the cultivars. Moreover, it also helps the plant convert other nutrients to optimize absorption.

Furthermore, it also contains the proper amounts of micronutrients. It includes traces of Boron, Carbon, Iron, Manganese, Molybdenum, and Zinc. Each contributes specific benefits but all aids in healthier growth and metabolic functioning.

This powder-based plant food is water-soluble. So, it is very safe to use, even with direct applications. This type of fertilizer will least likely cause harm or burn to your plants. Furthermore, they tend to be well absorbed much faster. Thus, enabling you to achieve more immediate results.

The Bloom Booster can be used in two different ways. You can opt to use it with a simple watering can. This is perfect for small and indoor applications. Another way is through Miracle-Gro’s garden feeder. This proprietary tool is very convenient to use, especially for more extensive outdoor gardens.

Miracle-Gro is also economical to use. A 1.5-ounce box is enough to cover a 600 square foot growing area when used along with the grow feeder. That is approximately equal to a garage room that can well fit three vehicles.

Things to concern:

Customers are quite disappointed with Miracle-Gro’s seemingly deceptive packaging. They tend to market their products in big boxes or containers. But the content in actuality, though, is not as much as you would expect it to be. Just know how much your product accurately weighs and don’t base it merely on the size of the outer packaging.

4. Advanced Nutrients Big Bud Liquid Fertilizer

Bigger buds simply mean bigger yield. 

Who doesn’t want to achieve that?

Advanced Nutrient’s Big Bud allows you to make it possible. This liquid fertilizer targets to give you larger, heavier, and denser flowers. As your harvest increases, so as your stash or your monetary gains.

Although, it’s not only the weight that matters. The quality of the resin per se is vital too. Big Bud fertilizer also helps to produce more essential oils, terpenoids, and phenols. Thus, further enhancing your bud’s aroma and potency.  This plus the heftiness of the buds is a surefire way to increase your yield’s total market value.

Like any bloom booster, this also contains a well-balanced ratio of Phosphates and soluble Potash. But, the good stuff doesn’t just stop there. This fertilizer also includes a great number of amino acids. In particular, the L-forms of Tryptophan, Cysteine, Glutamate, Glycine, and many others.

These amino acids play an important role in the development of plants. These building blocks of protein support the cellular and metabolic processes of plants. Moreover, it also helps them to produce energy and transport essential nutrients. It’s actually the same as how amino acids benefit us humans. 

But unlike us, plants are not capable of sourcing amino acids nor proteins from other organisms. Rather, they have to produce it themselves. So, if amino acid supplement is what your plants need, then Big Bud got you covered. 

Things to concern:

Advanced Nutrients Big Bud liquid fertilizer is a very popular product. On the downside, though, it is quite popular too for having poor and leaky packaging. It can be due to mishandling during the shipment or just not enough seal.

Magic Line:

For cannabis buds that are not only dense but tasty too.

• Contains magnesium and amino acids
• Suitable to use in soil, sphagnum, and hydroponics

5. General Hydroponics Liquid Kool Bloom Fertilizer

Liquid Kool Bloom is another famous fertilizer manufactured by General Hydroponics. This bulking plant food is rich in Phosphorus and Potassium that come in equal ratios of 10% each. With such, it promises to stimulate abundant flowering and ripening of your cultivars. 

Liquid Kool Bloom also supplements the plants with stress-reducing nutrients. Like humans, less stress means happier plants too. As a result, it triggers them to increase their production of essential oils. Making them more aromatic and flavorful in the end.

The solution can be both used as a stand-alone or as a nutrient additive. As a primary fertilizer, it is best applied at the very start of the reproductive cycle of the cultivar. That way, you have greater chances of producing larger and heavier flowers and fruits. 

But as a nutrient additive, the application should be done towards the last two weeks of the cycle. Doing so will further boost it to bloom and ripen.

Liquid Kool Bloom is suitable to use in soil, coco, and hydroponic grow settings. In general, a teaspoon or two of the fertilizer is being mixed for every one gallon of water.  

Things to concern:

General Hydroponics is a well-established brand known for its high-quality products. And, Liquid Kool Bloom is no exemption. Customers seem to be so pleased that it garnered hundreds of 5-star ratings on Amazon. So far, no major drawbacks can overshadow the efficiency of this fertilizer.

What to consider if you want to buy the best bloom booster fertilizers?

• N-P-K Ratio

Nitrogen, Phosphorus, and Potassium are the three pillars of fertilizers. These three nutrients often represent the main component of plant foods. 

Nitrogen functions to prevent overstretching of the cultivars. For cannabis, you would want to start with high doses of Nitrogen first. This will encourage vigorous growth of the plants. Levels are then eventually weaned off as it comes near the harvest period.

Meanwhile, Phosphorus and Potassium both help crops to optimize their bud formation. It also assists in the plant’s enzymatic actions. Opposite to Nitrogen, higher doses of P & K are much needed during the early and mid flowering stages. During the later phase, most growers terminate Nitrogen but keep P & K only.

That said, the N-P-K ratio varies depending on the certain phase of the flowering cycle. So, be aware that you might need different fertilizers to cover your plant’s entire blooming needs.

• Organic vs Synthetic Fertilizers

Organic nutrients are naturally a slow-release fertilizer. That is because the nutrients rely on other microorganisms to breakdown. Thus, the process takes a while before the plants can absorb the components. 

But in that same sense, it is also safer to use because it lessens the risk of overfeeding and burning the cultivars.  On that note, organic fertilizer is suitable to use by novice growers since it is more forgiving.

On the other end, there are synthetic nutrients. These fertilizers are being made from chemically-chelated nutrients. Its biggest advantage of using inorganic plant food is precision. This type of solution has the capacity to deliver exact ratios of N-P-K and other minerals. Thus, ensuring you get better control over your feedings. 

Unlike the organic, synthetic nutrients are not dependent on microbes. Thus, it is much readily-available for plants to absorb. It’s both a good and bad thing though. That is because it increases the likelihood of overfeeding and burning your cultivars. Considering the technicalities, synthetic nutrients are more apt for professional uses.

• Forms & Preparations

Bloom boosters are often available in powder or liquid form. Either way, always take the precaution not to apply it directly to the plants.  There are some that require proper dilution first. Dissolving the nutrient in water makes it a lot easier for the plant and its root system to absorb.

• Read the Label

Make reading a habit!

Different fertilizers have different nutrient contents, indications, preparations, applications, and more. It is not a one-size-fits-all kind of thing. Even if the solution contains the same N-P-K ratios or from the same brand, it doesn’t mean they’re already the same.

Take some time to read the guidelines the manufacturer had provided. This will help you get a better understanding of the product and its proper usage. Remember, once the nutrient is being administered, there’s no turning back already. It can either benefit or destroy your plants. So, try to learn about the product as much as you can to avoid careless mistakes.
