Help!!! My kids are dying

Ok so im in week 6 of vegg and i decide to spray the leaves with fertz. I come home a day later and this is what has become. (see Pics)

So i frealed and put them in a flush for 3 days and then on a backed off nute solution (350ppm instead of 600ppm where they were b4 the accident). So i have been running them at this and some of the big fan leaves were destroyed and have since fallen off.

Nothing has changed in over a week and they dont seem to be getting better and they dont seem to be getting worse. Please!!

Any suggestions would be helpful.

Man, I've seen all the leaves die and the plant still survive and bounce back, so be patient. stay with clean fresh water for a while, no nutes.

I probably would have kept the resevoir the same. I wouldn't ever foliar feed with whatever you used again. BTW what was it?

Disregard that. I seen you said you changed it and foliar feeded. The double whammy.
