I use AN with tap water.. I have been told the sensi line has a back door or lock out prevention because of its chemical makeup.. Its a very good nute line..
@Rifleman runs AN with tap in DWC buckets and dude pulls weight.

Just went ahead and ordered sensi grow and bloom, big bud, bud candy, and cal-mag. I wanted a root stimulator, but I guess they don't have one for sterile systems.
