Last night I mixed up 5 separate gallons of nute water I use Pure Blend Pro Grow and Bloom I used 3ml of grow and 10 of bloom I checked ppm and it was around 950s on all jugs. So I let it sit overnight and when I went to ph adjust it today only 12 hours later my ppm is between 571-617 on all jugs after adjusting to 6.6 ph. I can't figure it out where did 300 ppm go in a sealed jug?? Has anyone else noticed this? And could it be because they are organic based?

Holy crap. That is a lot.

What else did you do? What kind of water did you use? I haven't used these nutrients before, but it sounds like something we could all learn from...

The water is r/o with ppm of 9 to start with. The mix was fully done and shaken tested than the next day shaken retested and 300 ppm less well today I just used the water immediately after mixing it
