PH Up/Down Toxicity Issues

[golaker]

I recently purchased a R/O unit. I get 7.0 ph water now. After mixing nutes (fox farm and cal-mag) I have a PH of roughly 4.0

Question: Is it safe to bring the PH up to 6.5 using ph up? Or is that too much?

* I do not want to add hard water to raise PH

* Adding the r/o water after nutes have been mixed has little effect on raising PH, and im not sure how much I want to dillute my solution anyways.

Thanks for the help guys.

I'm pretty sure thats what ph up is for isn't it?

Get your PH correct and do so very quickly so nothing precipitates out. I mean like 5 minutes very quickly though

Yes...lol.....that's what PH up is for......

However, I have heard from numerous sources that too much PH up or down can/will make your nutrient solution toxic

I can just add PH up or down as I please? With no consequences whatsoever?

I find this hard to believe...

Mejuana: I mix the ph up/down immediately after stirring in all of my nutes.
