Remo Nutrients AstroFlower is a pk booster bloom enhancer for the flowering stage of growth, made to promote flower development and support bud development in horticultural gardens. This budding and flower product targets flowering-focused nutrition with a potassium and phosphorous emphasis.
AstroFlower is described as a potent source of potassium and phosphorous, selected for flowering performance rather than general, all-cycle feeding. It is designed for maximizing bud development when plants shift into bloom, with a clear focus on flower formation and finish. Many growers reach for a pk booster like this when they want a simple way to sharpen flowering output without changing their overall base approach.
A key part of AstroFlower’s identity is its support for essential oils and aromatics. That makes it a natural fit for gardens where aroma and fragrant expression matter as much as flower structure. The formula is also described as a precise blend of elements, keeping the product centered on flowering-stage results instead of broad claims.
For buyers who want a quick facts layer without the clutter, AstroFlower is 1-6-11, a straightforward NPK profile that reflects its flowering-stage pk booster role. The inputs are kept focused as well, with potassium and phosphorous at the core, plus humic and fluvic acid as part of the blend. AstroFlower also does not contain animal products, which matters for growers who prefer plant-focused inputs across their nutrient lineup.
AstroFlower is suited to soil, soilless, and hydroponic gardens, so it can fit into many common grow styles. This is a good fit for growers looking for a flowering-stage bloom enhancer that promotes flower development, supports maximizing bud development, and helps bring out essential oils and aromatics while keeping the product choice simple and direct.
Step-by-step mixing and feeding instructions for Remo Nutrients AstroFlower - 1 Litre.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Remo Nutrients AstroFlower - 1 Litre well before every use. Using the feeding schedule below, measure the recommended dose and add it directly to the water while stirring. Allow the solution to mix fully before adding any other fertilizers, additives, or supplements.
Always add nutrients to water — not the other way around. Mix thoroughly between products to ensure an even, stable nutrient solution.

Warning – Important Safety Information
This product may cause mild skin irritation and eye irritation. Avoid unnecessary contact with skin, eyes, and clothing. Use only as directed.
General safety precautions
Read and follow all instructions on the product label and any accompanying documentation before use. Keep out of reach of children and pets. Do not ingest. Avoid breathing vapours, mist, or dust that may be generated during handling or use.
Wear appropriate personal protective equipment (PPE), such as protective gloves, long sleeves, long pants and closed-toe footwear. When there is a risk of splashing or airborne particles, use safety glasses or other suitable eye and face protection.
First aid – skin contact
IF ON SKIN OR HAIR: Remove contaminated clothing immediately. Rinse skin with clean water for several minutes, then wash with mild soap and water. If irritation or redness develops and persists, seek medical attention. Wash contaminated clothing before reuse.
First aid – eye contact
IF IN EYES: Rinse cautiously with clean water for several minutes, keeping eyelids open. Remove contact lenses if present and easy to do. Continue rinsing. If irritation persists, obtain medical advice.
First aid – ingestion and inhalation
IF SWALLOWED: Rinse mouth thoroughly with water. Do not induce vomiting unless instructed by a medical professional. Seek medical attention if you feel unwell.
IF INHALED: Move the person to fresh air and keep them comfortable for breathing. If coughing, breathing difficulty, dizziness or other symptoms occur, seek medical assistance.

| Nitrate Nitrogen (N) | 1.0% |
|---|---|
| Available Phosphate (P2O5) | 6.0% |
| Soluble Potash (K2O) | 11.0% |
| Sulfur (S) | 1.0% |
| Chelated Zinc (Zn) | 0.05% |
| Humic Acid | 0.79% |
Available Phosphate (P₂O₅) supports root development, energy transfer, and early structural growth by providing a form of phosphorus that plants can absorb and use quickly.
Chelated zinc is important because it keeps zinc available for uptake even when pH or root-zone conditions would normally lock zinc out, helping plants form normal-sized, healthy new growth—something that makes zinc uniquely different from many other nutrients that mainly affect older leaves or simple leaf color changes.
Humic acid is important because it improves root health and nutrient uptake by keeping minerals available, stabilizing the root zone, and supporting beneficial biology, which makes growth more consistent. It’s unique because it doesn’t act like a direct nutrient boost—its main power is improving the root environment so plants can use what’s already there more efficiently.
Nitrate Nitrogen provides a stable, easy-to-absorb form of nitrogen that supports steady growth, strong foliage, and reliable plant development without sudden nutrient swings.
Soluble potash (K2O) is important because it helps plants control water use, move sugars to new growth and fruit, and build stronger, higher-quality structure under stress. It’s unique from many other nutrients because it acts more like a regulator and transport helper than a direct “building material,” so the biggest benefits show up as steadier growth, stronger stems, and better finishing instead of just bigger leaves.
Sulfur is important because plants need it to build key amino acids and proteins that drive real growth, strong structure, and efficient use of nitrogen, making it uniquely different from “look-alike” nutrients that may change leaf color without supporting the plant’s core building process.
Leonardite helps roots by improving the root zone’s ability to hold and deliver nutrients and moisture more smoothly, making uptake steadier instead of swingy. It’s unique because it mostly conditions the soil system through humic substances rather than directly feeding the plant like a typical nutrient source.
Monopotassium phosphate provides fast phosphorus and potassium that support energy use, nutrient flow, and bloom development without adding nitrogen, so it helps flowering progress cleanly without pushing extra leafy growth. It’s unique because it delivers a focused PK boost in a highly soluble form, which can correct stage-related demand quickly, but it must be used carefully to avoid potassium-heavy imbalances that can block calcium and magnesium uptake.
Potassium nitrate is often better for quick correction when the plant needs both potassium and fast nitrate nitrogen, because it dissolves cleanly and is taken up quickly, unlike potassium sources that don’t supply nitrogen. It’s unique because it can restore leaf color and growth momentum while also improving water regulation, but it can backfire if nitrogen is already high or if salt levels are already stressing the roots.
Potassium sulfate is often preferred because it supplies potassium without added chloride and also provides sulfur, which supports protein-building and efficient nutrient use, making it a cleaner, balanced option when plants are sensitive to chloride or when you want potassium without pushing extra nitrogen or phosphorus.
Zinc EDTA is important because it keeps zinc available in the root zone when pH or water chemistry would normally tie zinc up, helping new growth develop normally before deficiency symptoms get worse. It’s unique from other zinc forms because the EDTA chelate shields zinc in solution, making delivery more consistent when conditions are not ideal.
