Advanced Nutrients Flawless Finish
Regardless of what nutrients are being used you must always flush your plants for the last 4-10 days of the cycle in order to get rid of nutrients within it. Some people will happily flush with just plain water for this period. However studies show that when using a 'flush agent' you will purge more food from the plant and therefore get an improved taste and result.
Advanced Nutrients recommend adding Flawless Finish once to your tank at the start of the flushing period, ensuring the plants roots are soaked for a number of hours with the solution. After this the tank can be emptied and refilled with plain water and your plants watered as normal for the rest of the duration of the flush.
