You have lots of issues. Was the mother plant in the veg stage or flower stage. If flower stage it could take up to 5 weeks for them to root properly.

I have successfully taken clones from flowering plants...but on the cloning machine is take 4 weeks or more.

Now if they were taken from a vegging plant....and you have them in a tray with a humidity dome make sure the rock wool is sitting on top of something...some people use a towl....some use peralite....just make sure they are not sitting in water.

Now Have your done clones before????

It not real difficult....but you must follow some steps....did you use a clean scoupal or very sharp knife? when you dipped them in the jell....how long did they stay in the jell? I usually let them sit in the jell for 5 minutes or untill I have about 8 of them ready to put on the cloning machine....Who took the cuttings?....how did they travel from your buddies house to your house...did you put them in water....because they will dry out very fast....

I guess I need more information.
