Well I went too heavy on the poor buggers. I believe it was that I added too much Nirvana which overdosed the PPM and gunked up the rockwool. I think the plants were choking because they were quickly changing to yellow. I flushed and used minimal nutes. The next day it was much worse. I took out the plugs and noticed the worst looking plant had the gunkiest rockwool plug. I carefully extracted the remaining healthy roots from the rockwool under water and replaced the plug with fresh rockwool. I feel confident that at least one the dwarf mix will survive.
