I think if u use a digital ec reader u can get it right but not with tap water as u dont no the contents do u use a truncheon i use a blue lab truncheon RO would be alot better but u would need to no exactly what to add hard water and hard water nutes takes all the hassle out of growingBluter i thought I read this on ther website but was stoned so I think it said if it flashes between numbers then it indicates the middle num . Say it flashes between 1.0 and 1.2 then it's 1.1.. that's the way iv been doing it
