Wanu Water-Anyone know why it’s discontinued at my 2 closest markets?

We found this flavored nutrient water about a year ago and really love it, although when not on sale it’s kind of pricey. In the last few weeks both Albertson’s (part of Safeway/Vons group) and Sprouts have been clearing it out and shelf tags all say “discontinued’. Anyone know if there’s back story to this?
