Chow_13started grow question 4 years ago I'm Running a Recirculating Deep Water Culture System( hydro). Had PH dropping dramatically a few days back but did a full water change and everything has stabilized. Just Flipped to a 12/12. Does it look like that was the issue or is it nutrient toxicity/deficiency. Or Stress?
