When it comes to figuring out what to feed to your plants, you might feel a little overwhelmed. Once you factor in the specific needs of your plants, the quality of the soil, and the different types of fertilizers out there, you might be left wondering if all the trouble is worth it. However, if you don’t feed your plants properly, they aren’t likely to grow well or bloom at all.

You have to be aware of the quantity of fertilizer you use on your plants. If they overdose on fertilizers, they might start to decay. On the other hand, too little fertilizer can stunt the plants’ growth.

The fertilizer’s impact is dependent on its components too. A good fertilizer must contain nitrogen, phosphorus, and potassium as well as other essential minerals, such as calcium, magnesium, and sulfur.

If you’re looking for a great fertilizer to try, check out Athena products. They offer a wide variety of fertilizers to support your plants as they grow from seedling to flowering. Here’s everything you need to know about this brand of fertilizer.

What is Athena?

Athena Products Inc is a manufacturer of both liquid and dry fertilizer blends that are designed for commercial cannabis cultivators. They follow strict procedures to ensure that their liquid Blended line and powdered Pro line of nutrients surpass industry standards.

Athena Pro and Blended nutrients are made from multiple ingredients combined in specific ways. Listed below are the best products from each line.

It’s made with one of the safest root zone optimizing agents, hypochlorous acid. Derived from salt and a proprietary electrochemical treatment process, the result is a unique, plant-safe chemical fertilizer.

Due to its powerful oxidative properties, it keeps the root zone clean and free from unwanted material and mineral buildup. These special properties can lessen the mineral scale in irrigation systems.


  • It’s safe to use on plants in any stage of growth.
  • It’s effective as a final flush to get rid of the mineral buildup in your growing media and irrigation lines.
  • It has a very low TDS.
  • It can descale irrigation systems and decompose residual organic matter.

How to use

Regular use:

Use a diluted mixture of 2 to 5 mL per gallon of water for regular maintenance.

For cuttings/clones:

Athena Cleanse is a must for clones and fresh cuttings. Dip the fresh cuttings in a solution of Cleanse (10 mL per gallon) to improve cell health and increase immunity. Seedlings and cuttings treated with it have more vigor and are more likely to grow into robust plants. The treated roots will be bright white and bursting with tiny feeder root hairs.

Media/system flush mix:

Use Athena Cleanse at a rate of 5-10 ml/ gallon of water during the final flush to help reduce residual mineral buildup.

You can also perform this procedure at any time during the vegetative or flowering phases if the growing media or irrigation system develops a mineral imbalance or unwanted buildup.

Foliar applications:

Mix 375 mL of Cleanse per gallon water and spray evenly. Test it on a small area first to ensure that there’s no damage.

Athena Cleanse

Athena CaMg

It’s designed to supplement a growing media that requires higher doses of calcium, magnesium, iron, and nitrogen during the heavy growth and development phases. It can effectively correct common deficiencies without disrupting the overall elemental balance.

Best Practices for Athena Nutrients

  • Shake the products well before use. These products are run through a 1-micron filter before bottling, so any micro-particles you see won’t clog your dosing systems or emitters.
  • Use clean measuring instruments. Don’t put anything else into the bottle to avoid contamination.
  • To increase your target EC, always use equal parts A & B to maintain the mineral balance.
  • Don’t combine these products in their undiluted forms. It renders the formulas useless.
  • Store them in their original packaging, and keep them at a temperature between 45° F and 85° F. Exposure to the environment will reduce their shelf-life.
  • You can adjust the recipes as needed. Every cultivar and growing environment is unique, so it’s natural to make adjustments to maintain your plants’ health and vigor.
