Question About one Clone Question About yellowing leafs

I have recently taking cuttings for cloning and took two cuttings the same day. I took the cuttings at least 14 days ago and one has a strong root system and I already transplanted her. The other clone taken off the same plant on the same day has not rooted at ALL. What is the problem? How come it has not rooted one bit. Both plants were in the same dome and one rooted fine and the other is just not responding, however the growth on the top looks fine not drooping or anything?

Second question has to do with these picks if they uploaded right. What is the yellowing from. Is it from lack of phospherous, or over watering?

Some clones just won't take, if its been 2 weeks and no sign of any roots yet, there probably isn't going to be any. I don't know what your cloning technique was so there is no way to tell you what went wrong.

Looks like over watering to me.

tops can take way longer to root, I use an aero cloner and I had a top in there that took 3weeks to root! but since we dont know what medium you used I cant offer much help either

about the yellowing, it looks to me that your pot my be to small for that plant and the plant is using up your nutes (if you have been nuteing) to quickly? over watering?
