Radredfox I'm sure you were hoping for more clearcut answers: If I were you I would use yeast nutrient, especially if you are not putting in fruit. I think I have been lucky not using it in part because I am almost always making melomel and the fruit adds nutrients. Also, the honey around where I live is very dark, especially the fall honey which is mostly what we use because most of our fruit is ripe in the fall. We make up to 25 gallon batches so I think this year I will make half the way we have been and half using methods in the excellent article that hopfenundmalz linked to. The problem with mead as opposed to beer is in the time it takes to get results we will make another dozen batches and it will be a year later.We have had a good amount of rain this spring and our hives are pretty strong so there is a good chance that we will have a honey flow in a couple weeks so if I get enough of the lighter summer honey I will probably try making a plain mead and using nutrients. Now to convince my girlfriend to change her methods after 20 years...
