Hi it's possible that theyturn purple because plants got 3 different color pigments on their leaves red, green and blue, most time in autumn they turn orange oder red and some plants turn blue or purple,
So it can also be a natural reason
Nice grow :ok_hand::skin-tone-3::+1:

Hello @Peak81 ! The purple leaves is molybdenum deficiency and it is triggered by low temperatures. Happy growing ! :facepunch:

Hi @Peak81! Genetics, cold temperatures, cold solution/medium, or a Phosphorous deficiency can lead to purple stems. In your scenario, it's certainly temp-related. Is your daytime temperature 10°C? What about the night temp? That's under the safe zone, 15°c is the ultimate threshold where you won't encounter issues. Hopefully the sun is going to fix this next week. Keep us up-to-date and happy growing :facepunch:

Really its down to which phenotype it has. You could plant 5 seperate plants of the same seed and they all turn out different. Yes you can try forcing color with cold temps etc..but really it all starts with the seed. My shaman is a purple variety but typically 1/2 of the seeds will purple...mine has some purple areas and some green. The next seed may be totally purple or green, with the same planting conditions.
I do love those purple/black varieties though, she is a beauty . :v:

Hello! 3 things : 1st When the temperature get lower in the late flowering some plant foliage turns purple. -2nd- This could be genetic ( recessive or dominant gene ) -3rd- It can be a deficiency but I forgot which one and It's not what's happening here. I hope it will help you :+1::grin:
