Hi I'm a week and half into flower and I set my reservoir at 1.7 ec at the beginning of this week. I checked yesterday and they had drank half a res so I topped up with half strength nutrients, the EC is now at 1.5 is this too low? I'm using a Wilma system and my background EC is 0.5, ph 5.8 and drifts to about 6. Any help would be appreciated thanks.
