Leaves turning color at 6 weeks

[jcfromsd]

I have 2 different plants. I'm concerned about the leaves turning light green and some yellowing and sporting. Is this normal?

I'm not sure I know what "normal" is, but it looks like you could tweak your nutrients or your light intensity. It looks like you'll finish okay though. Those are some nice-looking buds!
