Nutri+ Blossom Plus (0-39-33)
Super-Concentrated PK Bloom Activator with Phosphorus, Potassium & GA3
Nutri+ Blossom Plus (0-39-33) is a highly specialized, super-concentrated flowering supplement designed to help initiate and enhance early flowering. Its powerful 0-39-33 NPK formula provides concentrated phosphorus and potassium together with rapidly assimilated flowering activators, including gibberellic acid (GA3).
Designed to be used alongside a complete base fertilizer, Blossom Plus provides targeted nutrition during key periods of the flowering cycle rather than continuous use. Its soluble powder formulation requires only a very small amount per application, making it a concentrated addition to an established bloom nutrient program.
Suitable for hydroponic systems and other growing media, Nutri+ Blossom Plus is formulated for precise applications during the early stages of flowering.

Powerful 0-39-33 Nutrition for Early Flowering
The concentrated 0-39-33 NPK profile makes Nutri+ Blossom Plus a specialized flowering supplement, not a conventional balanced fertilizer.
Its nutrient analysis provides:
- Nitrogen (N): 0
- Phosphorus (P): 39
- Potassium (K): 33
The absence of nitrogen keeps the formula focused on targeted bloom-stage supplementation, while the high phosphorus and potassium concentrations provide mineral nutrition suited to the reproductive phase of plant development.
Phosphorus supports plant energy transfer and reproductive development, while potassium supports numerous physiological functions throughout flowering.
Because Blossom Plus is highly concentrated and does not provide a complete nutritional profile on its own, use it with an appropriate complete base fertilizer rather than as a stand-alone nutrient. Biofloral describes Blossom Plus specifically as a specialized floral fertilizer used in addition to a more complete fertilizer.
High Phosphorus & Potassium for Flowering Nutrition
Nutri+ Blossom Plus (0-39-33) provides concentrated phosphorus and potassium at stages when flowering plants may demand more of these nutrients.
Biofloral describes the product as containing a very high dose of phosphorus and a high dose of potassium, combined with rapidly assimilated activators.
Rather than replacing the phosphorus and potassium supplied by a regular Bloom fertilizer, Blossom Plus provides a specialized additional dose during carefully selected stages of flowering.
This makes it particularly useful for growers with an established flowering fertilizer program who want to add a targeted PK bloom activator without replacing their existing base nutrients.
Contains Gibberellic Acid (GA3)
One feature that distinguishes Nutri+ Blossom Plus from conventional PK bloom boosters is the inclusion of gibberellic acid, commonly known as GA3.
Gibberellic acid is a plant growth regulator. Nutri+ includes GA3 specifically to influence flowering development, which is why Blossom Plus is intended for punctual, carefully controlled applications rather than continuous feeding.
The manufacturer recommends its first use during the first week of flowering, followed by another targeted application around the third week of flowering.
Because GA3 can strongly influence plant development, accurate measurement and proper timing are especially important when using Blossom Plus.
Specialized Early-Flowering Activator
Unlike a standard Bloom fertilizer used throughout the entire flowering cycle, Nutri+ Blossom Plus (0-39-33) is designed specifically for targeted early-flowering applications.
During the first week of flowering, the formula is intended to stimulate the transition into floral development.
A second application is recommended around the third week of flowering, providing another carefully timed dose of phosphorus, potassium, and flowering activators.
This targeted approach lets growers introduce the highly concentrated formula when it's most useful, without continuously increasing the mineral concentration of the nutrient solution.
Important Usage Note – Follow Dosage Carefully
Nutri+ Blossom Plus is an extremely concentrated and specialized product. More is not necessarily better.
Nutri+ specifically warns that improper use of the gibberellin contained in Blossom Plus can adversely influence flower development and may cause masculinization of flowers. For this reason, the manufacturer emphasizes respecting the recommended dosage.
Growers should therefore:
- Measure Blossom Plus accurately
-
Follow the recommended 1 g per 10 L dosage
- Apply only at the recommended stages
- Avoid increasing application frequency unnecessarily
- Do not combine it with another mineral bloom supplement at the same time
Nutri+ explicitly advises against using another mineral flowering supplement at the same time.
Helps Support Flower & Fruit Development
Nutri+ formulates Blossom Plus to activate flowering and support the development of denser, wider and heavier flowers and fruits when used correctly as part of a complete nutrient program.
The concentrated phosphorus and potassium provide targeted mineral nutrition, while the rapidly assimilated activators are intended to influence the transition into flowering.
Nutri+ also notes that the components in Blossom Plus can contribute to plant maturity and the accumulation of sugars, starches and essential oils.
Because plant response depends on genetics, growing conditions, nutrition, and environmental management, Blossom Plus should be incorporated as part of a complete flowering program rather than viewed as a replacement for balanced cultivation practices.
Helps Stabilize pH During Early Flowering
Another distinctive feature of Nutri+ Blossom Plus is its carbonates.
According to Nutri+, these carbonates help prevent a sudden drop in pH at the start of flowering, particularly during the first 7 to 10 days.
This feature can be particularly useful in hydroponic and intensive nutrient systems where maintaining a stable root-zone environment is an important part of plant management.
Growers should still monitor and adjust the pH of their nutrient solution according to their growing medium and crop requirements.
Designed for Hydroponics & Other Growing Media
Nutri+ Blossom Plus (0-39-33) is designed for use in hydroponic systems and other growing media.
Its fully soluble powder formulation lets you measure the required amount and dissolve it directly into water or an established nutrient solution.
Because Blossom Plus is a supplement rather than a complete fertilizer, growers should continue using an appropriate base nutrient program while introducing Blossom Plus only at the recommended stages.
This makes it easy to integrate the product into an existing feeding schedule without replacing the primary Grow or Bloom fertilizer.
How to Use Nutri+ Blossom Plus 0-39-33
Recommended Dosage:
Add 1 g of Nutri+ Blossom Plus per 10 litres of water.
This is equivalent to approximately:
0.1 g per litre of water.
First Application:
Apply during the 1st week of the flowering cycle.
Second Application:
Apply again during approximately the 3rd week of the flowering cycle.
Application Method:
Carefully measure the required amount and dissolve it completely in water or nutrient solution before applying.
Base Nutrients:
Use Blossom Plus alongside an appropriate complete base fertilizer.
Important:
Do not use another mineral flowering supplement at the same time as Blossom Plus.
Do Not Overdose:
Because Blossom Plus contains gibberellic acid (GA3), follow the recommended dosage and application timing carefully.
Super-Concentrated Formula for Efficient Use
With an application rate of only 1 g per 10 L of water, Nutri+ Blossom Plus is extremely concentrated.
Example mixing rates:
-
10 L: 1 g
-
20 L: 2 g
-
50 L: 5 g
-
100 L: 10 g
-
200 L: 20 g
Because you need such small quantities, we recommend using an accurate digital scale.
The concentrated powder format also makes Blossom Plus easy to store and lets even the smaller package prepare a substantial quantity of nutrient solution.
Works Alongside Your Existing Bloom Fertilizer
One advantage of Nutri+ Blossom Plus (0-39-33) is that it is not designed to replace an existing flowering fertilizer.
Instead, you can incorporate it into a complete nutrient program as a specialized early-bloom additive.
Your regular base fertilizer continues to supply the broader range of nutrients required by the plant, while Blossom Plus provides a targeted combination of:
- Phosphorus
- Potassium
- GA3
- Rapidly assimilated flowering activators
at specific stages during flowering.
This lets growers maintain their regular nutrient program while adding a specialized product only when needed.
Available in Multiple Sizes
Nutri+ Blossom Plus is currently available in:
The 20 g size is convenient for smaller gardens, occasional use and growers using smaller reservoirs.
The larger 300 g size suits larger growing operations, bigger reservoirs, or repeated flowering cycles.
Because the recommended application rate is only 1 g per 10 L, both formats can prepare a substantial volume of flowering solution.
Why Choose Nutri+ Blossom Plus 0-39-33?
