Looks like you over did it with the nutrients or you gave them too much of one nutrient without enough of another and they burned. Not a lot left to do, you can take them outside and just start running as much water thru them as you can. Like if they are in 5 gallon pots run like 20 gallons thru the pots and that may stop it from getting any worse but they will not come back from that.

I would still flush them but that is me. The stuff is going to be pretty harsh because that did not just start like last night, you can see some of the dead fan leaves brown and curled up. I would still flush to try and get as much of the excess nutrients out as you can. I wonder that you were feeding them and at what numbers because I have seen nutrient burn but that is really bad. If you can flush them at least it will help make what is left better but they are pretty cooked.
