Don't ever run plain water through coco, it will leech the Calcium and Magnesium off of the cocos' cation exchange sites which have a higher affinity for Potassium and Sodium and will be displaced by those ions.
Always run a low ppm nutrient solution if you are going to flush anything in coco.
Bluelabs truncheon is probably the biggest tool I have lol. It is definitely highly overpriced for what it does ($10 parts to measure electrical conductivity of a fluid). But mine has lasted like 20 years so it has more or less paid for itself. In any case if you are growing in coco it would be wise to have an EC meter of some sort.
