I could be wrong, so take this with a grain of salt...but I don't think you're going to be able to re-veg those plants. The flowers look too mature, and the main stem doesn't look like it'll retain much moisture anymore. They look "past their prime", so to speak.

But again, I could be wrong. I guess it could be entirely possible, as I've never tried re-vegging a fully mature plant before.

Regardless, those are some great looking buds!:thumbsup:
