My plant went from green and healthy to showing all of the symptoms depicted above over the course of a few days. I'm sure the cold doesn't help, but since the transplant there have been no new or worsening symptoms. This leads me to believe that TwistItUp was correct in his assertion that it was root rot. I would love to give the plant warmth, but a heat pad is not an option in my situation.
Im looking forward to more conducive growing weather. Got a 5 gallon bucket fermenting some fish hydrolysate, and a compost heap getting ready for spring. My next run will be much better than this one was. I didn't expect much planting so late, and to be honest I don't even know why I did it. Boredom I guess.
