trouble with cloning

for some reason i cant get any of my clones to take any suggestions

information on your methods would help.

Use very moderate light and expect it to take about 4 weeks. I use rockwool cubes, about 6 shoots per 4x4, using the plant's bottom shoots that would not have yielded much anyway. Water and a little B1 is all they get. Poke a thin hole in the rockwool, whatever you can find to use like the middle of a bic pen, to about 1". I don't even foilar feed or bother to put a dome over them, I just make sure the rockwool stays wet. I've gotten 100% using that method.
