that’s it right there I believe. I would try to get that temp up just a bit (72-75) at least till week 7 of flower myself. All and all I do not believe you have much to worry about, but if you can raise the temps, I believe you may find better end results. But this plant could be a beast and power right through like nothing hit her, this is where genetics joins the conversation. Otherwise, your garden looks great, and there is not enough purple that I would be showing too much concern if it is too much a bother to raise temps.
