3 weeks is way too long for healthy clones. It may take a week or so depending on how stressed (and how many green leaves they have left) the plants are to get them to come back around. I'd give them some clonex solution to help ease the shock of transplanting / moving them. In smaller containers with lots of foilar, the roots can sometimes grow faster than they look in their leaves. I had a set of REALLY buggy plants (so neglected their leaves were more white than green) I didn't want to plant for a couple weeks, so I left them in some 3" pots with some foilar and when I was working with them, many still had the white leaves, but their roots where dangling out the holes in the pots about 6" or so.
Just give them some time and some foilar/rooting food, they should come back around without a problem
