Grow Mediums ph rising in reservoir

[seedstodreams]

I've only grown in soil before this run and I just want to make sure everything is okay. I'm using tap water that I let sit for 24-48 hours with Canna Rhizotonic, A & B, and Calmag, adjusting ph down to 5.8 with earth juice crystals. After about 24 hours, the water in the res is at 7.0 ph but the ppm doesn't seem to change

2 autopot xl with 5gal fabric pots, using airdomes

I just adjust back down to 5.8 but I'm not sure this is okay lol

i use a 47 ltr res and i had lots of ph spikes wit a pump with this new food i was using emerald harvest so i took it out and it stopped but if your not using one all you can do is keep ph it down it may settle after this 2nd time bro
