Hey guys I'm having a little trouble with a sour stomper and a fugue state from mephisto genetics. The leaves are yellowing on the bottom and some of them look burned and discolored. They're under 2 600w quantam boards. They been fed an organic 2-6-6 top dress and cal mag pretty much every other time. I thought it was cal mag deficiency but now I'm not sure. I've attached pictures, any help is greatly appreciated. Thanks!
