They usually more brownish, but it might be close to their last stage of metamorphosis? Becoming pale green

Leaves are safe to consume- just use the green parts of the leaves.
I wouldn’t use anything on things you eat- the reason we grow our own- is to avoid chemicals used in industrial agriculture production
