EC Flush

[panel350]

Hi All ,I 'm growing in Coco and have just done a flush just to get the EC back in range .So I flushed the plant and the run off was 1.4 then I waited an hour and did another flush and the EC on that was 2.0 so just wondering if thats good or bad .
Cheers

Feed/water to 30% run off for the next two days. Coco with only an inert substance such as perlite needs to always be fed/watered until you get 10% - 20% run off. This provides a continuous flush, so you don't get a salt or nutrient build up in the root zone.
