It's my opinion the root rot is the cause of the pH drop. Root rot being caused by too high of a nutrient load, usually after physical flower bulking has ceased. Lack of oxygen and biological outbreaks can also cause root rot to skyrocket and pH to plummet.
I'm thinking my nutrient profile has been just a touch shy on calcium, making root rot easier to occur. We'll see.
