    check temps at nite, 55-50 faranheit will turn leaves purple, cant see in that pic tho, put it into whiter light... and take a pic of it then...

    some strains change colours through flowering, ive seen nyc diesel with pitch black leaves...

    usually when its a temperature problem, the veins will go purple before the whole leaf...

    good luck...

    so do you think if it was from low temps it would take anything away from growing up to its full potential
