some say photoperiod does it and then an expierenced grwng friend told me it's the temp? Long story short hw do you successful grow purple leaves and bud
The purple color is called anthocyanin and it is found in many plants. The blue color of blueberries is due to anthocyanin. Some cannabis plants are just naturally purple- their ancestors came from a colder climate and the anthocyanin's purple color helps soak up the sun. Some cannabis plants have sufficient number of anthocyanin genes that they can turn purple if they get too cold. Some cannabis plants you can freeze to death and they stay green. Granny
I am running a purple strain, and it really didn't color up much till the end. When all the hairs started turning dark brown/orange and i seen it had swollen all up.. and it was time to harvest (trichomes turning under microscope.. but i dont got that yet). anyways, i took the plant, and shoved it in a closet for 2 days in darkness.. pulled it out and it was super fruity and had fully colored out.. anyways, try a day or two of darkness and let me know if that makes your stuff color up.. note that i was using a purple strain though.. so it may be strain dependent i don't think it will work on just any plant.
yes without getting clones, I'm going to try on my last two days of veg and turn off the lights around 75 degrees. I'll post pics
