Description

Athena Nutrients Pro Line Bloom, Grow, Core is a dry soluble fertilizer trio designed to cover vegetative growth and flowering with clean, mineral-only nutrition for professional irrigation programs. This soluble mineral fertilizer set is built around clear roles: a soluble base fertilizer for baseline nutrition, a soluble vegetative fertilizer for early development, and a soluble flowering fertilizer for productive bloom.

Pro Core is the foundation piece, built to provide baseline nutrition across all stages of plant growth with readily available nitrogen, calcium, and essential microelements. That combination supports core plant functions like chlorophyll and amino acid formation, structural development, and the enzyme activity tied to photosynthesis. When you want a dependable nutrient backbone that stays consistent from start to finish, Pro Core keeps the focus on steady fundamentals rather than extras.

Pro Grow is focused on the vegetative growth stage, where well-rounded nutrition supports strong roots and lush foliage. It’s described as a soluble fertilizer blend formulated for commercial cultivators to streamline irrigation, with balanced NPK and essential microelements as part of the Pro Line approach. Athena also calls out a formulation choice: Pro Grow contains essential nitrogen for vegetative growth while containing no urea or ammoniacal nitrogen, keeping the nitrogen profile straightforward for professional programs.

Pro Bloom is built for flowering plants that demand higher phosphorus and potassium to increase flower bulk and support high metabolic activity. It’s positioned as an ideal flowering fertilizer blend that contributes macro- and micro-elements, including sulfur that Athena associates with increasing flavors. For growers who want a clean bloom-phase profile, Pro Bloom stays centered on flowering nutrition and sulfur-supported finish character, without leaning on separate boosters.

Across the line, the practical differentiator is cleanliness: each product is a fully soluble dry fertilizer with no particulates or sediment, designed to keep the formulation uniform and easy to handle in large-scale routines. The Pro Line positioning emphasizes a complete formula built to reduce deficiency chasing, with mineral-only inputs and a streamlined approach meant for professional fertigation environments.

The compact facts layer is clear on packaging: Pro Core is 14-0-0, Pro Grow is 2-8-20, and Pro Bloom is 0-12-24. Key inputs across the trio include calcium nitrate and a microelement chelate package in Core (iron, manganese, copper, and zinc chelates plus boric acid and sodium molybdate), and phosphate, sulfate, and magnesium sources in Grow and Bloom, with Grow also including potassium nitrate. This set is a good fit for professional growers who want a dry soluble fertilizer program with clean dissolution, essential microelements, and phase-specific support for vegetative growth and flowering.

Frequently Asked Questions
What makes boric acid important for plants compared to other micronutrients?

Boric acid supplies boron, which plants need in extremely small amounts to build healthy new growth and support flowering and fruit development, but the safe range is very narrow. It’s unique because deficiency shows up first in the newest tissues while excess often burns older leaf edges, so accurate diagnosis and tiny, careful corrections matter more than with most nutrients.

Read the full guide

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.

Read the full guide

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.

Read the full guide

Why do growers use calcium nitrate instead of other calcium sources?

Calcium nitrate is important because it supplies calcium in a fast, highly available form that supports strong new growth and healthy root tips, while also providing nitrate nitrogen for steady, usable growth energy. It’s unique because it delivers calcium together with nitrate nitrogen, making it especially effective during rapid growth phases when plants need both structure-building calcium and immediately available nitrogen at the same time.

Read the full guide

Why is chelated copper (Cu) important for plant growth, and what makes it unique from other micronutrients?

Chelated copper is important because it supports key enzyme systems that drive energy flow, strong tissue formation, and healthy new growth, while chelation keeps copper available and stable in the root zone. It’s unique because plants need it in extremely small amounts and it can become unavailable or toxic more easily than many other micronutrients, so chelated forms help deliver precise, predictable copper without big swings.

Read the full guide

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.

Read the full guide

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.

Read the full guide

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.

Read the full guide

Why is copper EDTA used in plant nutrition instead of plain copper?

Copper EDTA helps keep copper dissolved and available to roots longer, so plants can absorb it more consistently when copper would otherwise tie up in the growing medium. It’s important because copper supports enzyme activity and healthy new growth, and it’s unique because the chelate improves predictability while allowing very small, controlled copper dosing.

Read the full guide

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.

Read the full guide

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.

Read the full guide

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.

Read the full guide

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.

Read the full guide

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.

Read the full guide

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.
