I set-up my first box a few weeks ago and the plants are yellow and leave are browning up. I was away for a week and had a drip line running, but we also had several inces of rain during this time. When I got back the plants were yellow and I turned off the drip system. We had some rain over the past week, so I gave them no supplemental water, and the plants are getting worse. I've checked the soil with a moisture meter and it's in the moist range on all the squares. I'm thinking it's due to too much water, but I'm not sure. Here are some pictures of the plants.
