Grotek Final Flush
Available in 6 Scents:
FERTILIZER RINSE SOLUTION
Final Flush is available in six scents, is designed to remove excess salt from the growing media for a cleaner-tasting harvest.
Excess nutrients are stored in the plant's tissues by plants. Plants are forced to remove excess nutrients from their root zones and convert them into secondary metabolites, which improve the harvest quality. This results in a high-quality harvest that has the aroma and flavour you want.
Application Rate: 1L = 500L solution:
Flushing with water will only remove dissolved nutrients. Final Flush has powerful solubilizers which liquify, remove precipitated and absorbed nutrition.
Apply the Final Flush solution liberally to the container to address any nutrient deficiencies or salt accumulation. Let the excess solution drain out of the bottom.
If necessary, repeat the process a second time. After that, wait for one week before you resume regular feeding.
