small problem

[Squ1rrely]

ok so my reservoirs hav been doin somethin weird lately. the water gets real foggy and the ph goes up. if i let it go 24hrs it will go up 1.0. i'm a seasoned grower and i've never seen anything like it. the plants still look good but hav slowed considerably and the only factor that has been affected is this water issue. i've asked my local gro shop as well as a few friends that also gro and they all say the same thing. the only thing they r on is Humboldt County's Own Gravity. i use a little of Potash+ in one and they both get Zone root stabilizer. i took away the zone and it didnt change anything.
any help is appreciated

Is that a multi-part nute concentrate formula you're mixing?
Is this happening from the get go, when you first mix your res, or does it happen when you're trying to maintain, top off or add back to the res ?
Looks like it's precipitating in solution pretty badly.

the nutes i do use are two part dutch master. they're not on that rite now. the only things in the res are Gravity, a small amount of potash, and foliar feeding with Purple Maxx Snow Storm. wutever it is is coming off the roots. i'm changin the res daily rite now. i'm jus gonna try to re-adjust ph and top off.

looks like mixxing PH up and PH downnnn precipitating nuteesss flush and only use ph down or up not bolthhhhhhh

i do only use ph down. all they are on is water, ph down, root stabilizer, and 1.2 ml/gal of Gravity (0-0.1-0). and foliar feed once a week with purple maxx snow storm. thats it
