Help Dark patches on new growth

[PLreef]

My best guess is genetics. Like GreenAlchemist said some strains start to turn purple as they get older. I've had some start off super light green and finish straight up purple.

What have the temps been like lately?

I personally wouldn’t worry as it seems (to me) to be genetics. Some strains turn purple as they flip to flower, but I would keep an eye on it for sure.

Plants were germinated around April 1, now growing outside in 10 gallon fabric pots. 6 plants in total, 4 have theses dark patches on the new growth, but not all of the new growth. Plants are Blue Dream and Aurora Indica. Growing in southeast USA.
