£9.95

A concentrated final-stage flushing agent designed to help remove accumulated fertiliser salts and unwanted elemental residues from the root zone before harvest.

Advanced Nutrients Flawless Finish is a specialist 0-0-0 finishing and flushing solution for use once the normal nutrient programme has ended. Its chelation-based formula is designed to bind unwanted elemental ions and help clear accumulated fertiliser salts during the final flush.

Rather than functioning as another flowering feed, Flawless Finish is used in place of the normal nutrient programme during finishing. Advanced Nutrients combines chelation technology with stabilised chelates and magnesium sulphate to support the plant through final maturation while stored and residual nutrients are being cleared.

At the recommended 2ml/L application rate, the 1L bottle prepares approximately 500 litres of flushing solution, making it a practical size for regular use in hydroponics, coco and container-grown crops.

Why choose Advanced Nutrients Flawless Finish?

  • Purpose-made flushing agent – formulated specifically for the final flush phase rather than being another flowering fertiliser.
  • Helps clear fertiliser salts – designed to remove accumulated nutrient residues as the crop moves towards harvest.
  • Chelation technology – chelates bind unwanted elemental ions as part of the flushing process.
  • Stabilised chelates & magnesium sulphate – key components highlighted by Advanced Nutrients within the Flawless Finish formulation.
  • 0-0-0 analysis – no conventional NPK contribution during the final flushing stage.
  • Simple 2ml/L rate – straightforward to calculate for tanks, reservoirs and hand watering.
  • Use throughout the flush – designed for consistent application during the complete finishing period rather than a single final rinse.
  • Suitable across growing systems – compatible with coco, hydroponics and a wide range of continuous liquid-feed systems.

What is Flawless Finish suitable for?

Flawless Finish is intended for the final flush after the normal base nutrient and supplement programme has been withdrawn. It is designed for growers who want a dedicated flushing solution to help clear accumulated fertiliser salts and unwanted nutrient residues before harvest.

The point at which the flush begins should follow crop maturity and the expected harvest window rather than assuming every crop follows the same fixed flowering calendar. Once the crop reaches its finishing phase, Flawless Finish is used consistently throughout the flush.

Advanced Nutrients identifies Flawless Finish as suitable for coco coir and hydroponic growing. Compatible continuous liquid-feed systems include aeroponics, drip irrigation and emitters, nutrient film technique (NFT), flood and drain and deep water culture (DWC).

How to use Advanced Nutrients Flawless Finish

At the end of the feeding programme, discontinue the normal base nutrients and supplements and prepare Flawless Finish with fresh water.

Add Flawless Finish at 2ml per litre and use the prepared solution consistently throughout the final flush phase.

For 10L of flushing solution, use 20ml. For 50L, use 100ml. For a 100L reservoir, use 200ml. For a 500L reservoir, use 1 litre.

When flushing container-grown soil crops, apply Flawless Finish during each watering of the flush period. Advanced Nutrients recommends watering sufficiently to produce approximately 20% runoff from the containers.
