porxide or h202,it seems like your roots need some oxygen.Did any light get into your bucket? it will cause algae,make sure your bucket is black covered in mylar to refelect any type of light ? did your pump ever cut off at any point?? always make sure your water is cold.Warm water can also cause root rot.

Just some info I have gathered from doing research on DWC!
