Part A of Athena's 2-part liquid bloom base — clean mineral formula, drum-scale.
Athena Blended Bloom A (4-0-5) is the nitrogen and potassium half of Athena's 2-part liquid flowering base — used in equal volumes with Bloom B throughout the flowering phase to deliver targeted macronutrients and chelated micronutrients across any media or irrigation method. SKU LQB-BLA-55G ships in the 55-gallon drum format sized for commercial fertigation rooms.
Athena Blended Bloom A is Part A of the two-part liquid flowering base in Athena's Blended Line. Its NPK is 4-0-5 — nitrogen and potassium without phosphorus — because phosphorus is held in Part B (0.7-6-5) to prevent precipitation in concentrated liquid form. Running equal volumes of A and B reconstitutes the full flowering mineral profile at tank mix. The two-part split is a deliberate formulation choice, not a convenience compromise: it keeps calcium separated from sulfates and phosphates in the drum, ensuring a clean, sediment-free solution when diluted into your reservoir or dosing system.
Athena formulates the Blended Line in Los Angeles under ISO 9001 quality management. The chemistry is the same foundational mineral approach as the Pro Line dry concentrates, packaged as a ready-to-dose liquid for operations that prefer not to weigh and dissolve dry salts. Bloom A includes chelated micronutrients alongside the macronutrient backbone, providing effective uptake across a wider pH range and in any water type — RO, municipal, or well.
The Blended Line targets licensed cannabis and hemp operations that want a clean, program-based feeding approach without the mixing complexity of multi-part dry systems. Bloom A is especially practical for rooms running automated Dosatron or proportioner-based injection, where the liquid format drops straight into the injector without pre-dissolution steps. It's equally compatible with drip, DWC, aeroponics, hand-watering, and recirculating systems — the sediment-free formulation means no clogged dripper heads or injection valves.
The 55-gallon drum SKU (LQB-BLA-55G) is the right buy for flowering rooms turning over multiple cycles per year. At commercial dose rates, a single drum covers significant tank volume, reduces packaging waste versus 1- or 5-gallon jugs, and integrates cleanly into bulk liquid storage. Operations running multi-room facilities or multiple strains on a shared feed schedule will find the drum format reduces reorder frequency and cost per gallon versus smaller containers.
Chelated micronutrients are a core differentiator in the Blended Line. Chelation keeps trace elements — iron, manganese, zinc, copper, and others — bioavailable across a wider pH window than unchelated salts. In commercial production, where reservoir pH fluctuates with CO2 levels, plant uptake, and water source variability, chelated micros reduce the risk of lockout-driven deficiencies mid-flower without requiring frequent formula changes.
The formula is mineral-only — no organic compounds, enzymes, surfactants, or biological additives. That's intentional for repeatability: mineral inputs produce consistent EC responses and predictable runoff chemistry, which matters in programs built around daily or event-based EC monitoring and runoff EC targets. Equal-volume dosing of A and B keeps the mineral ratio locked throughout the flowering phase, regardless of whether you're in week one of flower or week seven.
Athena publishes a 13-week Blended Line feed schedule covering Propagation, Veg, Flower, and Finish stages with week-by-week EC and pH targets and a defined mixing order. Bloom A enters the program at the transition to flower and runs through the final weeks before Fade, with dose rates adjustable between 2–7 mL per gallon based on target EC and crop demand. The schedule is available directly from Athena and is designed to be used as a starting point, with adjustments based on runoff EC readings and plant response — particularly in coco and rockwool.
For operations pairing Bloom A with the broader Blended ecosystem — Bloom B, CaMg (for RO or inert media), Balance (pH buffer), PK (mid-to-late flower booster), and Cleanse (root zone and irrigation maintenance) — HSC carries the full Blended Line.

They must be used together in equal volumes. The two-part format keeps calcium separated from sulfates and phosphates in concentrate to prevent precipitation. Running only one part delivers an incomplete and imbalanced mineral profile. Always add them separately to a reservoir already filled with water — never combine A and B in undiluted form.
Yes. The sediment-free liquid formulation is designed for compatibility with dosing systems including fine dripper heads. Dosatron and similar proportioner setups are explicitly supported. If you're running electronic dosing systems (Netafim-style), verify compatibility with Athena's Balance additive separately — that product carries a specific note — but Bloom A itself works across standard mechanical and electronic fertigation setups.
Same core nutrient philosophy, different physical format. The Pro Line ships as dry, water-soluble concentrate — lower cost per gallon at scale, requires dissolving and mixing before use, and is the common choice for large commercial operations with dedicated mix rooms. The Blended Line is a pre-formulated liquid — no weighing or dissolving, faster to work with, and the drum format still scales well for mid-sized licensed operations. Both use the same EC-based, mineral-only feeding approach.
The chelated micronutrient system in Bloom A is designed to maintain effective uptake across a wider pH range than unchelated nutrient formulas. Athena's standard recommendation is to adjust pH after mixing all nutrients and additives — not before — and to monitor EC regularly. Athena Balance (potassium silicate) can be added first in the mixing sequence if you're working with RO water and want to pre-stabilize pH before introducing the base nutrients.
Yes. HSC carries the complete Athena Blended Line — Grow A and B, Bloom A and B, CaMg, Balance, PK, Cleanse, and Fade — including 55-gallon drum and 275-gallon IBC tote formats where available.
