Cloning Problems

Hey guys, I hope someone will be able to help me out here. I have been cloning different mothers and I have been having a problem ever time. My clones start out green and they will not root until I hit about day 21 and they look like this.

From what I understand my clones should be rooting faster especially since I am using the Turbo Kloner.

Sometimes clones do turn yellow after they have been taken and are trying to put out there roots i like to give my moms a little feeding a few days before they give me some kids. As far as taking 21 days to root thats alright depending on the strain some are harder to clone than other so success rates are often diffferent from strain to strain. Expierence does also play a factor but as long as your tempuratures and humidity are all right then your okay also be sure that your mother is as healthy as can possibly be. Cloning does take time think about it your performing an act of god pretty much this poor branch was cut off then stuck in cubs its stressful to the branch and it has to go through a whole process of changing its self and moving hormones around within itself to turn from just a branch into a new plant putting out those roots takes that time.

i have had full sativa clones that took a month to put out roots but once they did they took off and they were even a little yellow when they were transplanted but once they were fed they greened right up patience is the name of the game
