major problem first bubbleponics grow

ok so I have 6 plants in a bubblerponics sysytem. I veged them for 4 weeks and then turned off my lights for 24 hours then put in my 150 watt HPS. I came back to grow room the next day and one of plants was completely dead and the 5 others didn't look too good. Can someone tell me why this happened so I don't do this again? For more details about my grow go to my signature

Bro you cant leave the light off for 24 hours. Especially with bubbleponics, it's a sensitive system bro, you aren't using soil anymore (which can help a plant survive through HELL)

Sure your hoses didn't get kinked in the move. As stated above you must be VERY careful as you don't have soil to buffer your mistakes.

Turning off your lights for 24 hours will not kill your plants, bubbler or not. Most likely your air pumps turned off also, they need to run continuosly. Make sure your pumps are not turning off with the light. Ive done that before .... big time disaster.
