I'm confused.
Small bottle sprayers- is the purpose of this solution foliar feeding?
It is usually recommended not to mix your fert solution until right before you need it.
I don't know why it's rising, but one thing that comes to mind is are you using a 5 gallon pail that used to have joint compound in it? That's a really wild guess.
stinkyattic Reviewed by stinkyattic on . stabilizing ph question ok this is my prob, i have a 5 gallon reservoir filled with tap water, which is used to fill up the small bottle sprayers...the thing is that when i fill the 5 gallon i imediatly test the ph, and according to the reading i´ll lower it or raise it with the propper ph solution, until the ph reads between 6.3 and 6.8..The prob is after a couple of days i (take readings every 12 hours or so) the water ph in the 5 gallon container starts to raise usually up till 7.0...i just dont seem to understand Rating: 5
