I also noticed the hydroton drying out quite a bit in between cycles and getting all white and chalky on top so I upped the flood cycles from every 4 hours to every 3 hours.
And I was also thinking that the 400 cfm exhaust fan might be a little too much to keep running at night. Could that be stressing my plants and stunting growth? I could get a controller to half the speed at night but they are like $100 for a reliable one and I am not sure if I really need it. the space is 172 cubic ft. so the whole room cycles probably twice a minute or a little less due to ducting curves.
