Athena Nutrients Blended Line Grow A and B is a 2-part vegetative nutrient and liquid mineral fertilizer for the vegetative stage of growth, built to support robust vegetative growth in non-flowering plants. As a two-part base fertilizer, it’s designed to give plants a clean, consistent nutrition foundation when you want steady development and predictable results in a straightforward program.
Grow A and Grow B are formulated around balanced mineral ratios and essential nutrients that create conditions for optimal plant development. The formula is positioned to support the vegetative stage of growth with additional nitrogen for lush foliage, keeping the focus on healthy-looking vegetative growth without unnecessary extras. If you want a veg-focused base that stays simple, Grow A and B are built for that role.
This pairing is also designed as a sediment-free formula, which matters when you prioritize clean handling in active irrigation setups. Athena describes it as suited to dosing and irrigation systems, including fine dripper heads, so it fits growers who rely on consistent delivery through lines and emitters. The label also specifies hydroponic use only, making this a clear match for hydroponic systems where mineral consistency and cleanliness are key buying factors.
Here’s the compact facts layer many growers want upfront: Grow A is 4-0-1 and Grow B is 1-3-5. The inputs are mineral nutrient salts and chelated micronutrients, including calcium ammonium nitrate and potassium nitrate, phosphate sources such as monopotassium phosphate and monoammonium phosphate, magnesium nitrate and magnesium sulfate, plus chelates like iron EDDHA and iron EDTA alongside zinc EDTA, manganese EDTA, and copper EDTA, with supporting trace inputs such as boric acid and sodium molybdate.
This is a good fit for hydroponic growers who want a 2-part vegetative nutrient with balanced mineral ratios, a sediment-free formula designed for fine dripper heads, and a clean two-part base fertilizer that supports robust vegetative growth and lush foliage through the vegetative stage of growth.

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.
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.
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.
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.
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.
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.
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.
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.
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.
Total magnesium is important because magnesium powers chlorophyll and energy use, helping plants stay green, turn light into growth, and use other nutrients efficiently—and it’s unique because its problems often come from nutrient balance and uptake competition, not just a simple shortage.
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.
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.
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.
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.
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.
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.
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.
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.
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.
