the other day, my plants drank 2-3 gallons of water and the ec went to 3.1...they left the nutes right in the rez...That is why I adjusted my rez back to 2.1-2.3 using ph'd ROwater. hope this helps
latewood Reviewed by latewood on . topping off -- plain water vs. nutrients When topping off the nutrients, is it appropriate to add some of the premixed solution you made originally when switching? That is if a decrease in ppm is noticed, and the plants are eating the nutes. Why do some reccomend only adding ph 5.5 water to the nutes between switches. thanks for any replies. note: I leave my nutrients in for 10-14 days. 25 gallon rubbermaid (recirculating dwc) 830 ppm @ 19 days flower.
