I was thinking of doing the same thing to my Raspberry Cough (about a week or so from harvest), if revegging and saving a branch for cloning is worth the time. I've been using BP Farmer's Pride line on it myself. It's frostier than an ice cold Dogfish Head Raison D'Etre goin' down a PotChimp's neck!
If I have to wait until it shows signs of reveg to cut it for a clone it might be easier to just plant another seed and utilize the space for bigger things. Then again, I might not get the same pheno; Hell the seeds might not even be from the same plant. Just because they were all bought at once and at the same place doesn't guarantee anything. Beautiful plants man, looks like almost enough to keep me high for a week!
