mushy clon roots why ? is it from using the gel and the olivias solution ?

im a newbie also and im using a hydro medium we put the gel on the clippings and then later some guy said to use olivias cloning solution which how can we save these im trying to clip were they are getting mushy and just wait but 4 already died our hp is ok but our meter might be a pos. so im freaking out i cant let purple princess die i have 3 srans and i think its from putting that cloning solution in the water ... so do i empty the water out and redo it ??? can i save them??? its been 6 days no roots just mushy ends to the clippings and then death if i let the mushy stuff go up the root to the actual plant.
