LR2 is one of my very fav autos and the strain I used to document (meaning grew and smoked a LOT)...and graph my personal preferences..and to find a 'mean' and purpose for harvesting at a specific time.......I found I did not like the couch locky LR2 and much much prefered (just like Smashed)...plum cloudy....very few clear and even few amber.....LR2 for me usually went 63-65 days from seed....I love to watch the bud swell at the last....
As Bailer said, some autos don't amber......some do....but since I SET my goals on my predetermined preference, I never let any of mine get to amber, even if they're an auto that will...
From what I could tell with the small pic, your buds seem quite swollen!...
