I am running 5 gallon buckets with air stones and everything has been good for the first 3 weeks. This past Monday it was time to clean buckets change water and add fresh round of nutes to start week 4 of veg. The only thing different this time was I added a couple of capfuls of cal/mag to each bucket. When I pulled net pod off bucket I noticed the roots were turning brown and there was some yellowing on the leaves. I am using full line of fox farm nutes. If anyone can help solve this problem it would be greatly appreciated. This is only my 2nd grow so I am still learning. There is a pic attached of what one of the plants looks like. ![IMG_20141219_102031.jpg](/data/attachments/2415/2415060-3966e0553aa0aa81e73bb179a0ca277b.jpg)
