How long before they root!! help

Hi, i been cloning my cuttings in bubble cloner for 2 weeks now. I had only one root heres the pic






I have 4 that have bumps on them like this pic here (p.s the bump was there on the thrid day of cloning, but not rooted snice)





and the other 9 cutting have still look the same. They still look heathly but I have not seen any other roots in 2 weeks. Is it normal my strain is Master Kush.


I been cleaning the bubble cloner every week(adding some h2o2). Water temp is 74-78.


thanks,

Dude, I would like to help, BUT the pix are NOT up, try again please.......BB
One question: Water level in cloner?
It MUST be at least 1 inch BELOW stem ends.
BUT, pix, please
