Note Flush It will only work at it’s best if the plant is healthy and has good healthy roots.
Make flush up at 5mls/ltr this should give an EC of around 1-1.2.
Use flush as follows.
In pots and run to waste systems add flush until around 20% of the volume has run through the pots check the EC of this run off it will be above 1.2. Each time you flush the plants (every 1 or 2 days if possible) the EC of the run off will increase, often going off the scale of the EC meter, this is the flush working.
In recirculating systems check the EC of the tank/barrel and when this EC has risen to around 3 replace the Flush It in the tank/barrel. Note as recirculating systems continually run the nutrient over the roots this may happen in a few days.
After 10-14 days of flushing the EC of the run off will start to drop back to the starting levels of around 1-1.2 when this has happened you have successfully flushed your plants and should have a better product.
