Sorry, I think some people are getting confused here. The flowering pics are no longer an issue, as they have been harvested. The problem remaining is the mother plant. The root pictures are of the harvested plant. The last 3 pictures, the individual leaves, are pictures of the problem plant (mother Red Dragon).. She's not being cut down... because she's not even flowering..
So to clear up any confusion, here are the pictures and problems again.
My mother Red Dragon plant is in a 3 gallon 70/30 Coco/Perlite mix. She's about 3 1/2' tall, LST'd all over the place, into basically a 3 1/2' x 4' x 4' cube. Spider mites have been a very minor some-what ongoing problem in my garden, once it becomes warm enough, everything will be getting dumped outdoors, and the room sterlized and replanted with new unaffected plants. However, the problem remains.. She has yellowing older leaves, which turn very brittle and then brown. Foliage has become a bit lighter green, but I believe this is due to 2 flushing and plain water only waterings for the past week. Before flushing, pH was 5.8. Lock out wasn't an issue. After flushing pH is still 5.8, PPMs are low 200s now, the water I was using was about 115PPM tap water. I am going to slowly give her more nutrients now as I don't know what else to do and I don't want to starve her. She's a few months old, and has been growing like crazy despite these problems under a 1000w MH. But I fear if I can't control the problem soon that I will just junk her and start fresh. Reincluding pictures. Keep in mind these leaves go from what you can see in the picture, to completely brown and curled, and just crumble. More pictures of the leave are in the original post above
