ok so i've been at this for a couple weeks now, and everything was going great, i got a 600w hps light, hung it 30 inches above the plants, came out that night and 2 of my plants were sad, it's been 3 days and now every one of them has this wierd white/yellow stuff on them... this is my first attempt, did i kill them? any advice would be excellent, thank you!
