Grotek Final Flush Blueberry

The Final Flush eliminates excess fertilizer salts in the final stages of growth and can also be used to correct over feeding or for desalinization of reusable growing media

Formulated to remove excess salt from growing media to ensure a cleaner tasting harvest. Plants tend to absorb excess nutrients and store them in plant tissues. By purging nutrients from the root zone, plants are forced to convert accumulated salts into secondary metabolites that improve harvest quality. The result is a top quality harvest with the flavour and aroma you expect.
