Run fan/filter during lights out?

Currently in my flowering room when the lights go out, my intake, outtake fans, general over the top of the plants fan and filter turn off as well. I don't have an odor issue and my temps stay around 70 so I never thought to leave them on at "night". Is there any benefit of leaving them on? Keeping the air flowing?

You don't need to run your fan/filter in the dark cycle. However you do need air moving in the room all the time including lights out.

fresh air circulation should be around the clock to prevent blight & PM issues

Yeah as mentioned to prevent powdery mildew and later in flower to prevent bud rot. Doesn't need to be a large fan but the air should be moving a little everywhere. I use the flickering bic flame test so if the flame is obviously influenced by a little air movement I know I'm going to be fine.

Does anyone have a thought on rh of intake air in dark cycle. I mean fresh air not just air movement.

Thanks Bare.
