Purple buds wk3 genetic?

[Bio boy]

My week 3 flower bed organic has all plants in bed different genetics but lost labels, the middle beast has been purple since wk 1 and getting stronger
Does this look genetic or is she needing something being so big, others don't express it atall in same bed so assuming genetic

Very nice plants. Cooler temps can help turn the plants' colors to brown or purple. I love purple buds. Thanks for sharing your grow with us.
