Need help please

Hello I have a small setup but I am dedicated to this. However just a few hours ago I turned on my veg room tofind some clones I just got have mold and it's a fluffy white residue. I'm in a panic cause I have 4 mothers also in there. My questions are simple. 1 how can I kill the mold without damaging my crop or do I kill them and sulfide the room? Will those mothers even be worth keeping to flower?
