hijack clone +rep 4 input

hi guys im running into problems with my hijack clone it has been rooted for a few days i have put it in to canna soil and now the top is shrivilling up/ small new growth really strange anyone know why my clone is doing this they are getting brown tips is my soil too hot or something i have only gave em plain water had this happen to the last one

Brand new clones don't really need fertilizers, so if the soil is fertilized they are most likely being over fed.

i havent gave em anything yet the soil has got nutes in it temps are at 82 with co2 +rep 4 u both i will post sum pics at lights on im in soil as well i had this happen to the last hijack clone it grew out of it i have another ak48 clone behind it and shes doing fine i cant get my head round this one
