Looking very nice, how long did it take to get to this point since switching it back to 18/6? I'm curious because I've got a northern lights in re-veg (also trying to save genetics) under 24hr and felt mine took a long time to switch back. I've already got a thread in basic growing, but it has a couple pics if you'd like to see her for comparison sake let me know. My opinion is yours looks just as healthy as a first harvest and look forward to seeing how your flowering goes the 2nd time around, Good Luck.
