Liquid phosphorus-potassium flowering base — 275-gal tote for production-scale rooms.
Athena Blended Bloom B (0.7-6-5) is the phosphorus- and potassium-dominant half of Athena's two-part liquid flowering base, formulated for fruit- and flower-producing plants at every scale. The 275-gallon tote format is purpose-built for commercial operations running inline dosing systems with high daily nutrient volume.
Athena Blended Bloom B is the Part B of Athena's liquid two-part flowering base, paired at equal ratios with Bloom A (4-0-5) throughout the flowering phase. The two parts are kept separate in concentrate form to prevent precipitation between calcium-bearing salts and phosphate/sulfate sources — a standard engineering constraint in professional two-part liquid systems. Once diluted into the irrigation line at equal volumes, the combined solution delivers a complete macro and micro nutrient profile optimized for bud development.
Bloom B carries the phosphorus and potassium load in the pair, with an NPK of 0.7-6-5. The primary inputs are Monopotassium Phosphate, Potassium Nitrate, Monoammonium Phosphate, Magnesium Sulfate, and Copper EDTA — a mineral-salt formulation with no organic fillers or surfactants. The result is a clean, fast-dissolving solution that behaves predictably in closed-loop and drain-to-waste fertigation setups alike.
The Blended Line is built for operations that want a straightforward liquid program without the weighing, stock-tank mixing ratios, and dry-powder handling required by the Pro Line. It runs directly through mechanical dosing systems (Dosatron), automated EC-dosing systems, drip manifolds, and fine-head emitters without modification. No pre-dissolving required.
The 275-gallon tote format is the appropriate buy for licensed indoor cannabis or hemp facilities running multiple flowering rooms simultaneously, or any single room large enough that 1- or 5-gallon containers create a logistics burden. Tote-scale purchasing reduces per-gallon cost, eliminates frequent reorder cycles, and integrates cleanly into bulk nutrient manifold setups. Compatible media: coco coir, rockwool, peat-based soilless mixes, recirculating DWC/NFT systems, and soil.
The formula is sediment-free at normal operating temperatures and compatible with fine dripper heads, including sub-millimeter emitters. Athena notes that small amounts of micro-particles can be visible under certain storage conditions but confirms these do not affect mineral balance or system compatibility. Best practice: shake or agitate the tote before use and use clean measuring instruments — do not back-contaminate the container.
Chelated micronutrients in Bloom B (specifically Copper EDTA) extend uptake stability across a wider pH range than non-chelated sources, meaning the formula maintains efficacy even when source water pH drifts slightly before adjustment. Always pH-correct after all nutrients and additives are mixed in the final dilution, not before. Monitor EC routinely and adjust dose within the 2–7 mL/gal range based on crop stage, media, and runoff readings.
Athena publishes a detailed 13-week Blended Line feed schedule covering the full veg-to-harvest cycle, including weekly EC targets and transition timing from Grow A+B to Bloom A+B. The schedule is available in both standard and metric formats directly from Athena. Operators running coco or rockwool should treat published EC targets as a starting point and calibrate to runoff readings — irrigation frequency and drainage management affect uptake as much as solution strength in inert media.
Bloom B pairs with Bloom A on a 1:1 volume basis throughout the flowering phase, with optional supplementation from Athena's PK booster (0-4-5) during mid-to-late flower, CaMg for RO and soft-water builds, and Athena's Cleanse product for irrigation system maintenance. The simplicity of the Blended Line — two parts per stage, published feed chart, no dry-salt handling — makes it easy to standardize protocol across multiple cultivation staff and facility locations. HSC supplies Athena Blended Line products nationally to licensed cannabis and hemp operators.

Bloom B must be used alongside Bloom A at equal volumes to maintain proper mineral ratios. Part A (4-0-5) carries the calcium, iron, and additional nitrogen that Part B does not supply. Running Bloom B alone will result in nutrient deficiencies — the two-part system is engineered as a pair. Always add each part separately to the dilution water; never combine A and B in undiluted concentrate form.
Yes. The formula is sediment-free and liquid, making it directly compatible with mechanical Dosatron injectors and electronic EC-dosing systems. No pre-dilution of the concentrate is required before the dosing injector. Standard best practice applies: agitate the tote before connecting to ensure homogeneity, particularly after extended storage.
Athena's published Blended Line feed schedule provides week-by-week EC targets and mL/gallon dose recommendations across a 13-week program. The general range for Bloom B is 2–7 mL per gallon, used equally with Bloom A at the same rate. Start at the lower end of the published range for the relevant week and adjust upward based on runoff EC and plant response. Always calibrate your EC and pH meters before mixing.
Yes. The Blended Line base (Bloom A+B) is designed to stack with Athena's supplemental lineup. Athena PK (0-4-5) is typically introduced mid-to-late flower for additional phosphorus and potassium loading. CaMg is recommended for RO and soft-water builds where calcium and magnesium may be insufficient from source water alone. Athena Stack (kelp-based biostimulant) is commonly used through early-to-mid flower. Always follow Athena's published mixing order to avoid precipitation.
