I'm having the same problem but it doesn't seem to matter what nutes i'm using , it all goes back to 6.8 after a few hours . so i'm convinced its my water & as soon as my RO machine gets here I should be fine ...... hopefullyOriginally Posted by dubwise View Post
@dansbuds- I'm not trying to be the poster boy for Jack's, but this stuff keeps nice and balanced when it sits for a couple of days. When I used maxibloom or the gh 3 part I always had to adjust my ph on leftover nutrients. With Jack's I don't.
That's interesting... I've been using GH products (Flora, FNova,MB) for ten years now.... haven't noticed what you're talking about. Rock solid pH when it's just sitting there at room temp.
I mix up and let it sit for up to (and once in a while 'over') a week... no pH issues. Sounds like you're not letting the MB completely dissolve before setting the pH... I've had it change on me when I've done that
