Coco + Ebb and Flow hybrid system.

It was turning purple in normal temps 80-70 and we had some cold weather here so I cracked a window next to the tent during night. The top colas turned purple in about 3 days then the whole plant slowed down and stopped drinking water I stooped the cold nights and a few days later she started drinking again. The depleted leafs turn yellow then purple it was a neat experiment and the colors are nice to look at.
