Know before you buy
Yes, Athena Blended Bloom A is designed as part of a two-part system. You must use it in conjunction with Bloom B to provide the complete nutrient profile your plants require during the flowering stage.
While it is optimized for hydroponic systems, it can be used in various growing media. However, because it is a mineral-based liquid concentrate, you should ensure your irrigation system is compatible with liquid fertilizers to prevent clogging.
The 4-0-5 NPK ratio is specifically balanced to work in tandem with the other components of the Athena Blended line. The phosphorus required for your plants is supplied by the corresponding Bloom B component, ensuring a precise nutrient delivery system.
Store the container in a cool, dark place away from direct sunlight and extreme temperatures. Keep the cap tightly sealed when not in use to prevent evaporation or contamination of the concentrate.
Athena Blended nutrients are formulated to work best as a complete system. Mixing them with other brands can lead to nutrient lockout or imbalances, so it is recommended to stick to the Athena feeding schedule for the best results.
