How come the Ph will change?

[MisterE]

ROOTS sitting in water will change the pH... very very normal

Smoking around the grow while using air stones will change the pH..

And using a sulfur burner with air stones in your reservoir will TOTALY FUCK your pH....

So if i"m puffing down a pack of smokes and it's sucking into my airpump, my PH could DROP, or RISE? Any definitive idea?

I've been wondering about ph dropping in my hydro setup and that could explain some.

I run an air purifier, but maybe I need to move it closer.
