:+:the correct way to change your nutes:+:

there are nutes that base there readings on the .7 scale but most of the time it does state on the label what scale they use to determine their measurements. but if you dont realize this it can cause lots of confusion such as why am I burning up my plants my solution is only at 800ppm.

Yeah well, there's the key - you are supposed to realize it. ;-)

Supposed to do that after you add the nutes, I thought?? Thats how I do it anyway
I keep several gallons of ro water that is pH adjusted around and use it to mix nutes and dilute pH adjusters. But I then check it again after adding the nutes even though I know it won't change. By the way, if the addition of nutes drives your pH off target, then that's an indication your nutes aren't buffering the way you might prefer. IMO, the sign of a good nute pH wise is when you add it to correct pH water, it stays correct.

yes that is the key, but a lot of people dont realize it is the problem. as far as ph I used to set my ph before adding nutes, I seen a lot of fluctuation in the ph not that some is bad but mine was what I thought to be eradict for the first two or three days after a res change. so for the hell of it I added my nutes first and then checked the ph and it was spot on 5.8 without using any down only adding the nutes. once I tried this my ph no longer makes large fluctuations. it always stays within tolerance. this brought me to a theory that if your using ph balanced nutes and ph up or down they actually fight each other before they balance out. I am not saying this is correct or that it is in any way scientifically a fact but just my experience and thought.

Actually that's correct. Most nutes buffer pH to some level, intentionally or not. Anything in the water buffers pH to some level (makes it "want" to go there). That's why they say distilled and ro water cause pH swings - because it has no buffering and and is sensitive to any influence. If your water is buffered or stabilized to a level other than what you want, you indeed have to fight it to get it off that dime.
