I been doing the same..running my heater on low..day/night...keeping a steady temp of a wet 80 degrees... I say "wet" because I'm curing them in a spare bedroom...that I built a very nice..3 tier hanging rack in...
I'm in the process of going from dish..back to cable..so I don't have a home internet right now..and I can't post pics from my phone..
Been a good year.growing for me..just not a good year for keeping a updated grow blog...
But when I do update it..boy do I got a lot of pics.,
Your hanging brown leaf looks excellent.
