One thing I learned, apparently you can get purpling to the leaves even if your temperature changes aren't to an actual "Cold" temperature. She was running a little hot, around 86f overnight in the tent. I have been keeping it opened during the day to keep the temps cool enough. Most of the time the tent has been around 75 or so.
Anyway we decided to set the thermostat a little lower because Springtime is coming. We had a room temperature swing and the plants got a 85f to 70f hit for a day or two. This particular girl decided to purple up a few leaves as a result. She seems fine and is a matter of days away from harvest so there's no harm but it's interesting to see purple leaves for the first time in person. :-D
Day #68 - Moved everyone to the new, permanent grow space! She's fading into fall colors quickly but enjoying her last hurrah in her bigger, cooler, more airy home! Call it a retirement home because I think she's going to the chop within the next two days or so.
Day #70 - Tomorrow she gets the chop! Mainly because I don't feel like doing it today. :-D
@Budcoin, Very very couchy and time slippery. If you sit still everything is fairly normal, but if you get up and move it's a slideshow. Very mellow, potent, and stoney otherwise.
