Outdoor plant, leaves turning purple / black

[el_fantistico]

Hi Folks,

I'm a new grower and I have an outdoor female who's in full bloom. Over the past few weeks I've noticed the fan leaves slowly starting to turn purple and black. First it was a few, now it's 3/4 of the plant. The buds, however, are still nice and fluffy and green. The nights right now are getting to be around 10 degrees Celsius (50 degrees Fahrenheit).

Should I be alarmed by this? I've got about another week to go.

Thanks,

El Fantistico :smokin:

Hmm...some strains have a genetic predisposition to produce purple foliage, but black? That doesn't sound like genetics. On the other hand, colder temperatures can cause some abnormalities in purple strains...like causing the plant to turn a darker shade of purple. Maybe this is what's happening to yours.

Do you know what strain it is? Also, if you could provide pictures, it would certainly help others to ascertain what's happening.

hey man my plants doin the same thing...its the end of the year and the plant knows its gona get smoked so its sucking up the rest of its sugars and thc and what not from all the fan leaves.. then in turn the fan leaves themselves turn yellowish then brownish then just die and fall off sometimes leaving its purple/dark purple or even black stem. you can either leave them on or help out and cut it off. i leave it on just so it gets everything it needs you know what i mean...once its all shribbily i cut it off. hey good news tho . your plants almost done.

If they are turning black however it is not a good thing

mine were turning a purple color also once i moved them inside due to days of rain and lousy temps, they seem to be turning back to green and crystals are getting more developed it is a sativa which has about 2 weeks left to finish.
