unfortunately my foaf has no ppm meter. The roots are pretty healthy white looking. All I know is the tap water has a ph of about 8.

There was about 1 gallon of fresh water added through the pots earlier to try something different. The plants still look the same though.

There is some wierd tapering of the stem at the base of most plants though that is kinda freaky, along with some discoloring of the leaves and stems....

I wish my foaf had more experience. Also I wish that they wouldnt die and would all be perfect in the morning....Im so sad.
