stabilizing ph question

[OmegaVermelho]

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 why????is it the heat????does the solution take that long to dissolve????What??????

tks guys:D :D

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.

If this is municipal tap water EPA says it must NOT be below 6.5 or any higher than 8.5. And 8.5 water would suck actually. Not sure why you would ever need to raise the pH. Municipal water supplies do not vary that much, at least in the East they dont. As asked before, what the hell WAS this bucket used for ? Seems strange your pH is all over the map straight from the tap.

Yes, bottle spayers, cause the plants are only 4 days old...i use them just to keep the soil surface moist...i aint using any nutes :D ...the 5 gallon its like a huge bucket with a "lid" on it i use it so i dont need to go back and forth for water..

I dont leave in the US...my tap water ph is around 7.0...so every time i need to fill up the 5 gallon "bucket" i need to lower the ph between 6.3 and 6.8...but after a few days that same whater that shoul be in those values (let´s say 6.5) its already at 7.0 or more...that is my prob
