Roots can appear as quick as 72 hours or take as long as a week...it sounds like temp and solution is right assuming clones stock was healthy and you made clean 45degree cuts you should have roots in no time...i find the most common reason to not having roots is temperature either to high or to low......good luck
moses is right about temps, that is a key factor, but Roots can take longer than a week, even 2. Lots of factors besides temps. How much light are they under? Light schedule? How long are the stems? Are they in the water or out? Did you scar the stems? What stage and shape was the doner plant in? Is the container light proof?
You dont have to use the cloxex in a bubbler either. Do not need it, and adding stuff to the bubbler has caused some people problems...slime. Not saying it will happen to you, but you can clone just as fast with just water, no gel. Personally I would dump your rez, fill with new RO water. Some strains just take longer, and some like different water levels. I like the water just below the cuts, so it is mostly just bubbles splashing and the upper part gets more oxygen, with smaller mist like bubbles. Have had success with stems in the water, and just above, but too high and they will wilt. The roots grow much different tho. If you get the right levels, the roots grow much better and faster. Depends on your set up honestly. Bucket size, water height, and pump strength.
Hope this helps a little, answer some of the questions...it will tell everyone a little more about your set up. Cloning is easy, if done right. Problem is, what is right for me....may not be right for everybody and vice versa. Find what works for you, but my advice is to atleast dump your water and fill with some new RO water. It has only been 6 days, it could 2 days or 10 more. Just be patient, and make sure you dont get any rot or slime. If the evironment is good, some should show bumps soon and then once it starts rooting they will take off. Good luck.
roots can appear as late as 14 days or more tho, i have various results on various strains. If no roots has appeared within 3 weeks i would toss the batch and try again.
