Athena Nutrients for Indoor Plants – Review

Athena Nutrients fertilizers and solutions lined up for plant growth, in an industrial setting.

We all know that houseplants demand extra care and attention. You might be doing everything by the book, but they die.

This is because nutrients in the soil are soon exhausted and need replenishment in the form of fertilizers. Choosing the right fertilizer could be tricky as it could flourish your lovely houseplant or cause damage.

Remember! One shoe only fits some; choose your fertilizers according to your plants’ needs.

Athena products are organic fertilizers in different formulations that are ideal for various plants and growing conditions.

Read the ingredients and mixing instructions written on the packaging before applying any of these items to your plants.

Follow the link to learn about the feeding schedule. Adding nutrients to your plants could get tricky. Monitor the EC (electrical conductivity) levels to change the dosage according to the plant species and growth stage.

This article will review different Athena nutrients and their applicability to varying phases of plant growth.

1. Vegetative Phase

The period between germination and flowering is crucial and decides the plant’s fate. Thus, it is essential to take care of your plants at this stage and provide adequate nutrients.

Some of the Athena products ideal to use at the vegetative stage are discussed as follows:

Athena Pro Grow


This fertilizer has a good amount of phosphorus and potassium (NPK 2-8-20), which helps plants flourish through the vegetative growth phase. These nutrients help develop strong roots, followed by lush foliage.

Athena Pro Grow helps create healthy conditions for subsequent flowering. The soluble dry nature and low heavy metal content make it an ideal choice for houseplants.

How to Use It?

However, the product should be diluted with water according to the plant’s needs. Pro Grow works wonders with Athena Pro Core (rich in nitrogen).

Athena Grow A and B

The clean and straightforward liquid formula gives the best results when two products (i.e., Athena Grow A and Athena Grow B) are combined in equal quantities. The A part of this fertilizer has NPK in a ratio of 4-0-1, while the B part has 1-3-5.

This perfect balance enhances the rate of onset of bud production and increases the number of flowering sites. Moreover, the sediment-free formula is compatible with irrigation systems like fine dripper heads.

You can also use these nutrients for non-flowering plants in a carefully balanced way. It helps create optimal growth conditions like healthy respiration, photosynthesis, and root health.

How to Use It?

Add both supplements in equal quantities and dilute them with water (concentration varies between plant species and environmental conditions).

2. Flowering Stage

This is when plants start putting all their energy into producing buds and flowering.

Athena Pro Bloom

Athena Pro Bloom - Gardeners Yards

This product is rich in phosphorus and potassium (NPK 0-12-24), which help increase the flower bulk in the flowering stage. These nutrients are essential in developing heavy flower colas, indicating happy plants.

Also, the balanced set of macro and microelements supports high-metabolic activities.

How to Use It?

It is another low-heavy metal and fully soluble dry (with no particulates) Athena product that works well with almost any dosing system.

The Athena Pro Bloom should be combined with Pro Core to get the best results.

Athena PK

This liquid Athena supplement is handy for the mid to late flowering phases. The perfect blend of low nitrogen levels followed by additional potassium and phosphorus (NPK 0-4-5) ensures maximum flower production of your indoor plants.

How to Use It?

It is ideal for diluting the product with water and administering it at week 3 of the flowering phase. Combine this liquid booster with Athena Bloom A+B to get maximum results. Using the wrong nutrients at the late-flowering stage blocks the calcium and magnesium uptake.

Luckily, Athena PK, in particular, does not create nutrient blockages and helps plants thrive.

Athena Bloom A and B

The two-part base fertilizer is specifically designed for plants in blooming stages. The mineral ratio in both products varies; NPK of 4-0-5 for part A and 0.7-6-5 for part B.

How to Use It?

If you want your houseplants to blossom, dilute these nutrients with water (according to your plant’s need) and administer them during the flowering phase.

The chelated micronutrients in this product make it ideal to use in a broader pH range.

3. Any Growth Stage

Athena Cleanse

Athena Cleanse, a unique plant-safe fertilizer made from hypochlorous acid (toxic-free root growth promoter), is safe to use at any stage of plant growth.

Its oxidative properties clean the root zone and help your houseplants be healthy.

How to Use It?

This product could also flush or eliminate the mineral buildup in irrigation lines and decompose residual organic matter. Dip your seedlings and cut in this solution before planting in a pot/container to enjoy healthy plant growth.

It’s specifically designed to help indoor growers who usually face the root issues. The treated roots would have enhanced cell health, immunity, and tiny feeder root projections.

Athena Stack

This natural plant development stimulator is made from kelp extract. It could be applied at any time of the plant’s growth; however, the ideal time would be at the beginning of the flowering.

It produces solid aromatic flowers and could easily tackle a mild case of potassium deficiency.

How to Use It?

An exciting aspect of Athena Stack is that it could be used as a root drench or foliar spray. It is recommended to apply this nutrient between the final week of the vegetative phase and weeks 4 to 5 of the flowering stage.

Inhibit the application of this fertilizer once the plants stop growing vertically. Moreover, soaking the seed in this solution for 2 to 3 minutes increases the germination rate.

Transplanting or reporting houseplants could cause stress, but bathing roots in Stack solution for a minute would help avoid transplant shock.

It is recommended to conduct foliar spray only once a week in the dark (lights off) settings. Avoid foliar application after three weeks of flowering.

Athena Pro Core


The primary nutrient in Athena Pro Core is nitrogen, which enhances chlorophyll synthesis – which is essential for photosynthesis It also contains essential microelements that help produce enzymes and regulate metabolic reactions.

The higher solubility potential makes it safe for indoor plants at any growth stage.

How to Use It?

Dilute the stock with water and dissolve thoroughly. The dosage depends on the desired solution strength.

It works best when combined with either Pro Grow or Pro Bloom components.

Athena CaMg

Some plants need high calcium (Ca) and magnesium (Mg) levels to grow well. Athena CaMg has high concentrations of Ca and Mg, which would quickly fulfill your indoor plant’s nutrient requirements.

This nutrient is beneficial when the growing medium is coco, as it naturally contains a minimal amount of calcium and magnesium.

How to Use It?

Dilute the product with water and use it at any growth stage to get the desired results. Decide the feeding schedule according to your plant’s needs.


The organic Athena nutrients are safe to use and affordable. It is possible to use these products for houseplants to enhance growth at any stage. Some Athena products become more efficient when used in combination with other products.

Try using Athena nutrients to make your indoor plants flourish.

A few standard practices when using Athena nutrients include shaking the products well before use. To avoid contamination, use clean measuring instruments. The dilution with water is essential for activating the formulas, which otherwise remain useless.

All the recipes could be changed according to cultivar, growing conditions, and plant health.
