UPDATE DAY 28
I noticed the girls on the autopots looked "droopy" this morning. I had the feeling it was either over or under watering. When I used my water meter it said they were both bone dry??? I lifted them out of their bases and there was a good 1/4in of soily water under each of them. Am i doing something wrong???? why are they not drinking? I stopped the flow at the res, undid the hoses, emptied out the brown water from each of their bases and fed them topside by hand.
