New DWC System Ph Climbing Wildly

and as a FYI since we're on the topic, if you need to fix a Mg issue really fast, foliar spray with about 1 TBSP per gallon right before lights go off. (don't do this when you have flowers or you risk mold).
 
Thanks man, will see how it goes next few days. Pushed my EC up 0.1 and PH down 0.1 so I gave it a bit of fresh water to mellow out back to what it was (1.4 EC 5.5 PH)
