I have been through a little of everything with my first grow. My first two I started together. They turned to herme. But that turned out o be good cuz I have one now and she's so big and wide another would not have fit in my 4 x 7 room.She was in the back part of the room when I discovered the others being herme. So I didn't tend to her much. She got root rot. I cured that. Then she grew so big and beautiful then this happened. She's not as green and full. I have fed her pH 6 water all the time, but I never got a 6 reading with my meter. Even today she was a 7. But I purchased some dolomite lime and will follow it tells me to do. I will start out light. I was told to slow down. I have done very little other than watch water intake, and watch it turn yellow ALL the big leaves have died off. But she's not yellowing, just the brown, which I found everywhere that says its over nuted. But I haven't given her hardly any nutes. Hopefully the MG soil isn't my main prob. Thank you all. I will post back if it has improved
