Hesi HYDRO PK 13/14

During the flowering stage of a plant's life, its metabolism is pushed into high gear producing large amounts of enzymes. It continues to grow larger increasing the need for nutrients to keep it healthy. That's where Hesi PK 13/14 comes in. 

The addition of PK 13/14 in the nutrient solution increases the level of phosphorus needed to produce increased enzymes, and potassium to get the phosphorus into the plant for it to utilize.

Hesi PK 13/14 is balanced to coordinate with Hydro Bloom and Hesi Coco nutrients. It should be added at the middle of the flowering stage at 2.5 ml to 10 Liter of nutrient solution and gradually increased to a ratio of 15 ml to 10 Liter nutrient solution at the second to last week of flowering.

13% Phosphorus
14% Potassium

Application Rate: Add in 4th week of blooming at 2.5 ml per 10 Liter of nutrient solution. Gradually increase up to 15 ml per 10 Liter at end of flowering stage.
