so we are like 3 months in to vegg...and the last week or 2 the PH up has been acting weird. it has been taking literally like half a cup of PH up to get up like .5 to .6 with 5 gallon drums... while PH down still just takes 6 drops or so. It use to just take 6 drops for PH up to. I'm not sure why this is happening. we have well water...maybe its something with our water softener? we just started using the pre evolution filter with our Evolution RO 1000 we have always used. anyone have an idea we calibrate our ph meter so thats not it
It may be that the sensor in your PH meter may need to be replaced. Just had the same thing happen to mine.
I`ve noticed that there PH Up isnt nearly as strong as their PH Down. Have you made any other changes such as adding a new nute or additive or a different brand? Were not on well water or use a water softener so not sure about that.
