The smell jumped from not so much to a lot. Mild light burn is visible on leaf tips. It was trying to rust before I refreshed my reservoir and stopped whatever it was from getting .
I am going to use Mars Hydro's dwc bucket kit for this run. My first run with my homemade dwc had a few flaws that this system basically corrects. Systems great just be sure to set up your buckets before adding the rocks. I can't select my nute line but it's there behind the lines working to supplement plant health.
