Does ph UP and Down change PPM?

[simondetroit]

Hello, When I add my nutes should I wait a while before I adjust my PH? I've been adding my nutes and then running a couple of pump cycles in my Aero setup. Then I adjust the PH. It seems like the next day my PPM is usually higer? Any ideas?

How much higher?

Why don't you adjust Ph right after adding nutes? Your ppm should jump up depending how much water your plants are drinking. Yes Ph up or down effects your ppm's slightly...

Thanks for the reply. I am adjusting the ph right after adding the nutes. I'm running botanicare nutes and using gh ph up and down. It seems like th ppm goes up around 75 to 100 ppm after I add enough ph down to get my 15 gallons of tap water from 7.5 to 5.7? And then within 24 hours it seems to go up an additional 25 to 50 ppm?

My guess is that is about right, considering you are using tap water..I found that you use a lot less PH up or down with RO.
