Athena Ag PK

You should introduce PK during the mid-to-late flowering stages. It is designed to support the plant's transition into heavy bud production, so wait until your plants have established their flower sites before incorporating it.

Nitrogen is essential for vegetative growth, but it can actually inhibit flower development if provided in high amounts during the late flowering phase. By removing nitrogen, this formula allows the plant to focus its energy entirely on bud density and terpene production rather than leaf growth.

While it is formulated to work seamlessly with the Athena Ag system, it is a clean, water-soluble mineral fertilizer that can be used alongside most other nutrient programs. Just be mindful of your total parts per million (PPM) to avoid nutrient burn.

Like most mineral fertilizers, adding PK will likely shift your pH levels. Always add your nutrients to the water first, mix thoroughly, and then test and adjust your pH to the desired range before feeding your plants.

Yes. Because it is a clean, liquid formula that is fully water-soluble, it is perfectly safe for hydroponic reservoirs, drip irrigation systems, and coco coir setups without clogging your lines.

The application rate is 4 to 15 mL per gallon of water. We recommend starting on the lower end of that range to see how your specific plants respond before gradually increasing the dosage.
