New Grower- In Flowering Stage

Whats up everyone

Im a NB and right now i have no idea what to do. So i have a hydro system with 9 plants. Plants were great and still look ok(about 30 inches tall) My lighting ballast went out but i have it back now. The normal light was not in for 8 days and my plants are HURT. The flowers dont look like they are developing anymore but instead look sick. the color has gone from the amazing green that it was to this dark nasty brown-purple color. the smell is not to great either. I dont know if I should toss them, cut the flowers off, keep going, or what.

If anyone can lend some advise I would be SO happy.

dvs.. if you have smell., you need to change the water in you reservoir NOW NOW NOW...

Are you on a 12/12 light cycle..

30 inches is very tall...
