Please help if you can. I've had my system up and going for 2 years. I've not had any problems until recently. I harvested lettuce and snow peas and they have a distinctive aroma and flavor. It's like a musty, mildew sort of smell, not good. I have a couple ideas what it might be, but I'm not 100 percent. I recently changed over to an organic feed and I added some michorrhizal fungi to see if it would have any effect. Hopefully this is not the effect. Is anyone else having this problem? We're you able to isolate the cause?
