Big Bud Liquid 1 Liter, by Advanced Nutrients, is a flowering stimulator designed to promote flower development at the stage when the plant requires the highest levels of phosphorus (P) and potassium (K). Its formula combines a balanced PK ratio with L-form amino acids and compounds such as ascorbic acid, with a clear objective: helping the plant produce denser and heavier flowers without complicating nutrient management.
In this guide, you will discover what Big Bud Liquid is, how it works in practical terms, when to apply it, how to dose it (soil and hydroponics), and which technical details (EC, pH, and compatibility) truly make a difference. If you purchase it from Hydroponics Blanes (growshopweb.com), it is important to understand its proper use in order to achieve maximum results without overfeeding.
What is Big Bud Liquid and what is it used for?
Big Bud Liquid is a flowering additive developed to strengthen the flower formation and bulking phase. It is typically integrated into a feeding program as an extra “boost” when the plant is structuring flowers and beginning to increase their density.
Its main function is not to replace the base fertilizer, but to complement it at the correct stage of the cycle. That is why it is known as a “flower booster”: it provides nutrients and cofactors when the plant needs them most.
Goals when using a flowering booster
- Greater floral mass (more volume and density when other parameters are properly managed).
- Improved flowering efficiency (fewer airy flowers under proper lighting and climate control).
- Better performance during key weeks (when the plant defines its final production potential).
Big Bud Liquid Composition: the essentials explained clearly
According to the product information, Big Bud Liquid contains:
PK focused on flowering
- Phosphorus (1%)
- Soluble Potassium (3%)
- Potassium sulfate
- Monopotassium phosphate
- Magnesium
Phosphorus plays a role in energy processes (ATP) and tissue formation, while potassium is essential for water regulation, sugar transport, and overall flowering performance. Simply put: when the plant is producing flowers, it mobilizes a large amount of energy, and potassium helps optimize this process.
L-form Amino Acids
- L-Alanine, L-Arginine, L-Aspartic Acid, L-Cysteine, L-Glutamine, L-Glycine, L-Histidine
- L-Hydroxyproline, L-Isoleucine, L-Leucine, L-Lysine, L-Methionine
- L-Phenylalanine, L-Proline, L-Serine, L-Threonine, L-Tryptophan, L-Tyrosine, L-Valine
L-form amino acids are interesting because the plant can use them as already “pre-built” components to synthesize proteins and enzymes. This does not mean an instant effect, but it can support the plant during periods of high metabolic demand.
Organic Acids and Other Components
- Ascorbic acid (Vitamin C)
- Citric acid
- Proteins (whey protein)
Ascorbic acid is associated with antioxidant functions. In cultivation, it may help the plant better manage oxidative stress (intense light, occasional heat). Citric acid can contribute to nutrient solution stability and solubility.
Technical note for recirculating hydroponics
In recirculating systems (DWC/RDWC), any organic component may promote biofilm formation if water temperature is too high or system hygiene is inadequate. It is recommended to keep water temperature between 18–22°C, with proper oxygenation and regular maintenance.
How Big Bud Liquid works during flowering
The principle is simple: during a specific flowering period, Big Bud Liquid provides an extra supply of PK + amino acids to support flower development. The best results are achieved when:
- Lighting is sufficient.
- Climate is controlled (temperature, humidity, balanced VPD).
- The base nutrition is already well balanced.
- It is used within the correct time window.
When to use Big Bud Liquid: recommended weeks
- Apply from week 2 to week 4 of flowering.
This period corresponds to the phase when the plant actively structures its flowers. Applying it too late will have limited impact, while applying it too early may cause excess salt buildup.
Dosage and how to use (soil and hydroponics)
Standard dosage
- 2 ml per liter of water
- Apply through irrigation during the recommended window
Technical recommendations
1) Monitor EC
The ml/L dosage is a guideline. In hydroponics and coco, the final EC is the key parameter to avoid overfeeding.
2) Adjust pH after mixing
- Hydroponics: pH 5.5–6.0
- Coco: pH 5.8–6.2
- Soil: pH 6.2–6.8
Common mistakes to avoid
Using it outside the recommended window
Replacing the base fertilizer
Ignoring plant signals
Forgetting that light is the priority
Using Big Bud Liquid correctly makes the difference
Big Bud Liquid 1 Liter is a flowering stimulator designed to reinforce the key phase of flower development. When used properly (weeks 2–4) and with adequate EC and pH control, it can effectively complement a balanced feeding program.
