some purpleness in my stock- just started budding cycle yesterday

hi guys, i just started flowering yesterday and i noticed that the stocks on all 3 of my plants were slightly purple half way up the stock......... anyone have any input?

twenty seven people have looked at this post but no one has any knowlege whatsoever? wow.......

Well it could be genetics or your plant is lacking something but if it appears healthy then no worries

thanks, i have two ak47 and one purple/bubba kush cross
