Hi everyone. I am on my first grow. I spend two weeks at a time away from my plants because of work. So I have my roommate water them while I am gone. But when I returned this morning my plants looked sick. I am growing 3 plants and 2 out of the 3 don't look good. The leaves are yellowing and drooping considerably. And when I walked into the room it didn't smell right. I believe the 2 sick looking plants are OG kush And the other is white widow. I want to say it is root rot but I don't know for sure. I am using an organic soil with earth juice bloom and grow. And a 180w led grow light. I might have improper drainage as I am not using perilite or anything of the sort. Just soil. I turned my lights back to a 12/12 schedule on January 2nd. So my plants are in the budding stage. Now I have heard of the fan leaves turning yellow in the later stages of budding. Could this be a possibility? They look generally unhealthy though. I need to know what you guys think and what my next moce should be. Thanks
