well, without pics its a bit guesswork.
how old are the plants? did you bareroot them, or did you transplant with the entire root system intact? did you transplant into the same general medium, or did you change completely? did you water enough after transplant?
like i said - its just guesswork without more info, bro.
i tried to keep as much of the roots together as i could but a couple broke, and i did change the medium, from mud (thats why i changed it), to a good home made compost mix. and i gave it a lot of water when i was done.
