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?
