Thanks for the advice. I'll make sure it's conveyed. She went ahead with it. Said it hasn't shown any negative signs yet (she did mention the pH was much more stable). My guess is the addition of all the bicarbonates to the system. she did allow the sugar/peroxide tea to sit for quite sometime without introducing it to the nute solution. so my guess is that most of what's left is peroxide (which people run in their systems quite often, though it may wipe out some of the bennies) or sugar (which will feed the bennies that were in the nute solution) IDK, we'll see. Maybe she lucks out and has all the right shit in place. Or maybe she has to deal with a flush and about $10 nutes wasted.
