I leave fan on all the time but it's getting cold now and doesn't need it at all now. Purple leaves . What strain you growing ? Could be that. the cold can turn them purple too. Pictures are worth all the help in the world. You get much more help when we can see the prob's.

Leaving the fan on under normal circumstances is a waste.-usdi Agluga

There's wind at night too, it wont hurt them. I keep the fans on 24/7.

Now that winter is setting in I don't use the fan as mine are mature and don't need the fan for good stem strenght. They do get fresh air from the central heat that pumps right into the grow space under the house.
