Damn. That's probably what it is then. I noticed that it was happening to all the outer leaves which were exposed to the most cold. I think she would be doing ok, but I pruned away her shaggy coat, and all the cold got right in there...
Maybe i'll bring my little 750 watt heater again. Do you think it would do her any good to heat the roots with a fan heater?
The color doesn't equal damage. That said, 12c is a bit uncomfortable for cannabis and could slow growth. Purpling by temperature is plant specific but mostly occurs around 65c and below. I have gone to 55 and saw slowed growth in most strains, saw purpling in some plants that didn't purple at 60, my usual target temperature. A small heater may be worthwhile or not. I assume you don't know this cut intimately so i would look at getting a heater in there. That all said there were no physical symptoms noticeable and the root balls weren't any lower temperature wise than they get at 60(root ball normally stays 10 above, at 60 mine are usually 71-73). The color is simply anthocyanins being produced in response to the cold air temperature. It is not indicative of damage and doesn't negatively impact photosynthesis or growth. It does replace the yellow you would normally see below the green though so it could hide hunger and chlorosis. It is not indicative of ph problems or lockout or nutrient issues. Lastly, typical ceramic and other heaters dry the air a lot. Humidity can become an issue if you don't have a lot of plants or a humidifier to maintain it. Further to that though ive never seen a problem so long as humidity is at least 30ish. Might not be ideal but wouldn't be a pressing issue and wouldn't slow growth like the cold would.Damn.

No...just the opposite. It works like a geothermal heat.Thanks for the tips. I was under the impression that water would make the effects of cold worse. I guess I'll just let my plant weather it out. I put the heater oscillating back and forth on the leaves for a little boost. I noticed that the main cola seemed to have actually sped up growth over night.
