Tex are you saying your pH swings down? whats your EC?
I have to actually move mine, the ph sits pretty much where i set it for a week or so...
My ec ride from .8 to 1.3-1.6 max in flower

plants absorb nutrients and water at different rates making your PH vary all the time. Hydro more so than Soil. I grow in Sphagnum and use a soil ph tester and fertilizer meter. Also I use a ph checker everytime I mix batch of nutrient solution or even plain water I Ph balance it to 6.3 .. Hydro is ideal at 5.8. If you use aPh meter for your nutrient solution be sure to pick up some calibration solution too. If not your Ph will get outta whack and have you kicking your dog.. and no dog deserves to be kicked unless he's eating your buds!
It's my understanding that as a plant gives up an H+ for a nutrient cation the concentration of H+ ions increases thus lowering the pH.
And as the plant exchanges an H+ for an anion the concentration goes down thus increasing pH.
I could be wrong.
I have been getting swings from 5.8-4.2, after 4 days, I have started adding ph up to bring it higher. Is his recommended?
