When you discover the leaves of your cannabis plant are turning purple while they should have a bright green color you either bought the wrong strain or there's something wrong with the plant due to weather or nutrients.
Purple leaves/buds generally appear on the so called "purple" strains like Blue Berrie and Bubbelicious but even then it can occur the plant stays green.
There are different reasons for the leaves to turn purple and even then it is hard to tell what exactly is going on because i think it is a combination of several factors.
Many people think it's a Phosphor or Kalium shortage but if that is the case the leaves should also change into other colors, for instance with a Kalium shortage the center of the leaves show a yellow color and within days the leaves will appear scorched.
The main reason for your green plant to turn purple is simply because along with the end of the season the nights get colder, this usually results in purple leaves because the roots aren't able to gain Phosphor or other nutrients from the soil that should keep them healthy in growth and color.
Logically when you grow indoors it is generally a shortage of certain nutrients that make the leaves turn purple, when you grow outdoors it is very admissible cold temperatures or swift temperature changing is the reason for a shortage of the right nutrients.
It is very important to take measures as soon as you detect this unique purple coloration, that means instead of giving your plant extra nutrients, first try to move her to another spot or make sure the roots don't get too cold.
If that doesn't help you can slowly give her more nutrients.
If you're not able to move the plant to warmer surroundings you can try aluminum foil or other isolation material wrapped around the pot, if your plant grows in full soil you can place isolation material on the soil she is growing in.
