How long has it been since you put them in? I was so consumed with checking my first time, I started looking for roots from day one and getting madder every day I didn't see them,lol. I have had some clones work that has less than three nodes, so there is hope, but the "dudes in the know" say to cut after the forth node and it's the forth node you dip....and remove the lower leaves and cut the fan leaves to half their size but leave the smaller leaves alone. BTW, I use Rockwool to root my clones, you just wait until you see the roots coming though and then just leave it in the cube and put in right in the soil.
