My guess? To re-veg them?
I would not recommend that choice.
Clones take 6/26 would now be two weeks old and started with veg state hormones.
Clones taken now are two weeks younger and will take a week or two to resettle their hormones back to veg hormones.
If one waits until the clones have stretched in flower one now has even younger clones that are still full of flower hormones AND are leggier.
might be useful to prove a point if compared to clones taken earlier, other than that? .....
