Description

Athena Nutrients Blended Line Bloom A and B is a two-part flowering nutrient, a liquid fertilizer for flower- and fruit-producing plants in the flowering stage. Built as a clean two-part base nutrient, Bloom A and Bloom B are designed to deliver complete flowering nutrition in a streamlined, easy-to-understand format.

This blended liquid formula focuses on plant-ready mineral nutrition that supports bud and flower development when demand increases. Athena formulates Bloom with macronutrients and chelated micronutrients to promote greater nutrient uptake ability across a wider pH range, helping key elements stay available when conditions shift. The result is a flowering-phase fertilizer that stays centered on consistency and reliable performance, not extra complexity.

Bloom A and Bloom B are positioned as a sediment-free formula, which is a practical advantage in hydroponic environments where cleanliness matters. The formula is intended for hydroponic use, making it a clear fit for growers who want a dedicated hydroponic nutrient for the bloom cycle. If you prefer a straightforward two-part flowering nutrient that keeps the profile clean while targeting flower development, this pairing stays true to that goal.

Here’s the compact facts layer shoppers look for. Bloom A and Bloom B each carry their own NPK: Bloom A is 4-0-5, and Bloom B is 0.7-6-5. The inputs are mineral nutrient salts and chelated micronutrients, including calcium ammonium nitrate, potassium nitrate, and phosphate sources such as monopotassium phosphate and monoammonium phosphate, alongside chelates like iron EDDHA/EDTA, manganese EDTA, zinc EDTA, and copper EDTA.

This is a good fit for hydroponic growers who want a clean, sediment-free liquid fertilizer and a two-part flowering nutrient built for the flowering stage, with macronutrients and chelated micronutrients supporting bud and flower development.

Frequently Asked Questions

What Is ammoniacal nitrogen (N) and why do plants need It?

Ammoniacal Nitrogen (N) is a plant-available form of ammonium (NH₄⁺) that provides a steady, gentle source of nitrogen for healthy green growth. Unlike fast-release nitrogen types, ammoniacal nitrogen feeds plants slowly, helps stabilize root-zone pH, and works well in cooler temperatures. It is commonly used during early vegetative growth because it supports strong leaf development without burning young roots. If plants show pale leaves, slow growth, or weak stems, they may need more available ammoniacal nitrogen.

Why is boron (B) essential for strong plant development, and what makes it different from other micronutrients?

Boron is essential because it stabilizes cell walls, supports root and shoot growth, and regulates sugar movement throughout the plant. What makes boron unique is its limited mobility and extremely narrow range between deficiency and excess, which causes new growth to show symptoms rapidly when levels fall out of balance.

What makes calcium ammonium nitrate unique for plant growth compared to other nitrogen sources?

Calcium ammonium nitrate is unique because it delivers quick-acting nitrogen while also supplying calcium that supports strong new tissue, so you can drive green growth without sacrificing structure. It’s important because it can correct slow, pale growth and reduce calcium-related weakness at the same time when the plant is in a rapid growth phase.

Why is calcium important for plant growth?

Calcium is important because it builds and stabilizes plant cells as they form, acting as the structural support that keeps new growth strong and functional. Unlike other nutrients that drive color or speed of growth, calcium’s role is unique because it controls cell wall strength and membrane stability, making it essential for healthy roots, shoots, and long-term plant resilience rather than quick visual results.

Why is chelated iron important for plants, and what makes it different from other iron sources?

Chelated iron is important because it keeps iron usable for plants even when growing conditions would normally lock iron out, helping prevent the classic yellow-new-leaf symptom caused by low chlorophyll production. It is unique from other iron sources because the chelation protects iron from becoming insoluble, making it a more reliable way to correct iron-related chlorosis when regular iron can fail.

Why is chelated manganese (Mn) important for plant growth?

Chelated manganese is important because it keeps manganese available for photosynthesis and enzyme activity even when pH or water chemistry would normally lock it out, and it’s unique from similar micronutrients because it strongly supports the plant’s energy-processing systems that drive healthy, resilient new growth.

Why is chelated zinc (Zn) important for plants?

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.

Why is molybdenum (Mo) important for plant growth?

Molybdenum is important because it helps plants convert nitrogen into usable building blocks for chlorophyll and growth, and it’s unique from many nutrients because it mainly supports enzyme-driven “nutrient use” rather than directly building plant tissue.

What does nitrate nitrogen (N) do for plants?

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.

Why is soluble potash (K2O) important for plants?

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.

Why is total nitrogen (N) important for plant growth, and what makes it different from other nutrients?

Total Nitrogen is important because it directly drives leafy growth, chlorophyll production, and overall growth speed, which sets the pace for the entire plant. It’s unique because the “total” number can include different nitrogen forms that behave differently in the root zone, meaning the same total amount can produce very different results depending on the nitrogen type and plant stage.

Why is water soluble magnesium important for plant growth?

Water soluble magnesium is important because it quickly restores the plant’s ability to make chlorophyll and produce energy, which helps stop interveinal yellowing on older leaves and improves overall nutrient use; it’s unique because it becomes available immediately in water, making it faster and more predictable than slower magnesium sources.

Why is Iron EDDHA better for plants growing in high-pH soil?

Iron EDDHA is important because it keeps iron usable when alkaline conditions would normally lock iron away, helping new leaves stay green and growth stay strong. It’s unique because it remains stable and plant-available at higher pH where many other iron forms quickly stop working.

What makes iron EDTA effective for fixing pale new leaves?

Iron EDTA keeps iron dissolved and available long enough for roots to absorb it, which is why it can quickly improve new growth color when iron is tied up in the root zone. It’s unique because the EDTA chelate balances stability and accessibility, making iron more reliably usable in mildly acidic to near-neutral conditions compared to many non-chelated iron forms.

What does magnesium nitrate do for plants?

Magnesium nitrate supplies fast-available magnesium for chlorophyll and photosynthesis while also adding nitrate nitrogen that can speed up greening and growth. It’s unique because it can correct magnesium-related yellowing quickly but also changes growth momentum, so it’s most valuable when magnesium is truly limiting and the plant can safely use extra nitrate.

What makes manganese EDTA different from other manganese sources?

Manganese EDTA is unique because the EDTA chelate keeps manganese stable and more available during delivery, helping plants absorb it more reliably when manganese would otherwise lock up. This matters because manganese drives key enzyme functions tied to photosynthesis and healthy new growth, so consistent availability can prevent pale, chlorotic young leaves and stalled vigor.

Is potassium nitrate better for quick deficiency correction than other potassium sources?

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.

What does sodium borate do for plants?

Sodium borate mainly supplies boron, a micronutrient plants need in tiny amounts to build healthy new growth and develop flowers and fruit normally, but it’s unique because the safe range is narrow and too much can quickly cause tip damage and leaf burn.

What does sodium molybdate do for plants?

Sodium molybdate supplies molybdenum, a trace micronutrient that helps plants convert nitrate nitrogen into usable building material, so growth and green color stay steady; it’s unique because it works as a tiny-dose “nitrogen unlocker” rather than a bulk nutrient.

What makes zinc EDTA better for preventing zinc lockout?

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.
