Bubbleponic clones need help?

So, i have a diy bubbleponic cloner, clones have been in almost 14 days now and most have the beginning of roots, im just seeing really slow root development. here are some pics. that one plant is far in front of all the rest. These clones were taken from mothers two weeks into flowering, so i expected slow reversion, but the quick growth. They are under 24/7 25 w cfl, tap water ppm 80-100 and ph 5.8-6, with 17ml 3% h202/l. three large airstones and dual outlet air pump.

Anyone offer any thoughts? Is this slow? the first second and fourth pics are all the same plant, the first two at day 13 and the last pic at day 9 1/2.

Hey man, do you know if the stem of the clone has to be above the water to gently get misted by the aerated bubbles? or can the stem be partially submerged in the solution? sorry i can't answer your question, as this is my first attempt at dwc hydroponics, but your feedback would be much appreciated!

Um, i have since cloned succesfully both ways. my clones seem to root fully at 21 days almost every time. I think that some of the biggest factors are strain and water temp. you just need to find what works for you. If they havent rooted in 30 days there's something wrong. Otherwise it'll happen just wait and wait and wait some more.
