2 reasons: genetics, of course. Also phosphorus deficiency. With P deficiency, it's often caused by colder nighttime temperatures which make the plant burn through P like you'll eventually burn through the plant. Add some P and the spread will stop.
I can't really see it in the pictures very well. Let me ask you a couple of thing: is the yellowing homogeneous (is the whole leave yellow)? Or is the yellowing more pronounced near the tip and the base still green colored? The former is nitrogen deficiency, the later is potassium deficiency. Do you notice rust colored (like burned) tips and edged in leaves? That's a more pronounced stage of potassium deficiency. At this stage it would be strange to have a nitrogen deficiency, since it's so late into flowering. My bet is potassium
I can't wait to try this and others from the fast buds auto's line, but this one most of all, really looking forward to seeing your harvest and hearing about how she smokes.. Good luck with the rest of the grow mate

@@@Athos, not sure. It sure looks more like N deficiency. I think from what I read, that it may have been a ph shift. I'll be posting more pics in a few days.

The yellowing on the pics in the link look just like mine
These look great, I’ve been having such trouble finding these seeds I was really wanting to grow them next but looks like I’ll have to try something else
