I am trying to figure out how anything can grow (even the plants some times) in my system lol.. If you smell anywhere in the system it just smeels like bleach lol.. I use more than a hospital does to do cleaning :P....
And the discoloring is centralized around where the
nutrients are sprayed onto the medium... Though the color does drip off with excess water when I pick up the plant. I am not sure what is going on or what inexpensive methods I can take to try to get rid of everything other than the plants that are growing lol.. Regretfully the grow medium I am using makes it more obvious when something is happening. If I were using rockwool, or clay pellets, I probably wouldnt have noticed the coloring there..
I was thinking it could be damping off on one of my plants due to the way it is acting. One of the basil plants are getting browning in the stem and starting to lean a little. So I will see if I can convince that one to stay alive. If I can't the basil were not the plants I was focussing on to want to live, so I will not to be too upset.
