My leaves are yellowing once again...need some marijuana wisdom in here.

Nice looking plants. They are not overfed...only lack of light on lower leaves.

You think so? Like, the leaves aren't dying off too fast, they just seem to be yellowing fully, then start to die.

I' also know that some of the original fan leaves turn yellow and die off during flowering. I just want to make sure this isn't too, too serious, as it seems to be slowly climbing up the plant.
