say if some one had a timer malfunction the 2 400’s are on a separate timer then the 1000 all in the same room, veg state ,but the 1000 never went out at night it stayed on but the other 2 went out on time …what would do ? 24 HR dark then back to 18 on an 6 off ???
Just get back to your “regular” lighting schedule - NO harm is done and many have had light issues like your’s - with every grow some dam thing will always go wrong that’s the fun of it ???
