Yea, mine took about 3 weeks, they looked really bad. 1 of them actually bent all the way over and was facing the ground for a while but ironically they are in their 5th week of flowering right now and that one is the tallest, healthiest plant. Just a heads up, the way I did it was straight from Jorge Cervantes Grow Bible. If you dont have this book, I highly recommend it. I am a second time grower now and that book saved the day more than a few times. But anyway, I also noticed that the smaller clones seemed to do a lot better, a lot faster. I took from the lowest part of my vegging plant on the last 2 i did and they ended up overtaking the bigger clones I took which were about the size of the one you have in the picture. I cut the last 2 clones about an inch below the 3rd set of leaves and then cut off the 3rd set of leaves(lowest set). I then had about 1 1/2 inches of stem from the leaves down. Then I took a sterilized razor and split the stem at the bottom about 1/2 inch long and scrapped the outer layer of the stem off for that 1/2 an inch(I mean very carefully and lightly, hardly taking anything off. Then I just dipped them in "Clonex Rooting Compound" and stuck them in a rock wool cube that I had soakin in "Olivia's Cloning Solution" adjusted to 5.8 PH. Another thing that I did on my current set of vegging plants was I started giving them Flora Nova Grow at 150 PPM(Flora Nova Nutes are what I use all the way through)after the first week because they all were rooting well and man they took off. I only did this as a test because the book says not to give clones any ferts early because it can kill the root hairs but I figured 150 ppm couldn't hurt because my water here is 230 ppm; I do have an RO filter now but I didnt when I started from seed and I watered the seeds with it and the plants did fine). I hope this helps because I know how it feels when they look like that but now I have all the faith in the world that I'll have good success with cloning because they went to hell and back and are doing outstanding right now!!!!
