Purple fan leaves at 11 weeks flowering?

[4x5]

These are From two different plants, same bagseed strain, never come across purple fan leaves, I am 11 weeks into flower, only about 40% cloudy trichomes. These two remaining specimens have a lack of yellow leaves(molasses and water off and on since week 8 when my other plants finished), they still have most of their fan leaves, but they are turning purple. I'm not worried, but is it strain or just nutrient defficient?

It looks like standard deterioration of the leaves at that stage of life.

That's what I figured, I've never had it before, the fans always yellowed and died.

seems to be right, like my sativa shed her leaves like 3 times now, grew back more healthier.

11 weeks into flower?? I cant think of any reason it would take that long.

yeah tell me about it; it's looking like these two will take 13 weeks, they are 32" tall, my trichomes are still less than 50% cloudy and all my test smoke from them has confirmed they are not yet ready.

Nice, purple 'fall foliage'.
No worries. Green chlorophyll is deteriorating and allowing other pigment colors to show; the red is instead of yellow- plants that don't have the red pigments would have just turned yellow when the green chlorophyll had broken down.

Maybe I'll post a fully deteriorated pic for example :stoned:
