Im feeding the plants with 2.0 Ec im in week 6 floweing (which it might be a bit higher than it should)
My question is this i gave plants just water and the run off of the ppm was 2.2-2.4 ,,, if i give the plants just water for the next 2-3 watering will ut bring it down or its salt build up and just flushing with plain water will fix it
Ph is lower around 5.7-5.8 due to the high Ec in the soil i water with ph of 6.0-6.5
Watering plain water will generally bring it down, unless you are using high ppm water. Unless you see signs of burn or lockout you should be fine without flushing. If you are having an issue with buildup, start watering to runoff.
