It depends on the temperature. Try to maintain 80-82 degrees at the canopy, with no more than a 15 degree drop at night, preferably no more than 10. If you can't get your temps to a respectable level without the fan at night, you'll need to use the fan. I have no ventilation at night in my mother, veg, or flower sections unless the temp is above 70 (using an atmospheric controller). I know people say this is wrong, but I've been getting lots of good weed for years. Consider though that my humidity stays at around 30. If you have high humidity it may be a different story.

I gradually change to bloom nutes over 2 feedings, once I change the light schedule. Bloom nutes are important if you want some good buds.
