I generally just dump the lees down the sink after racking. You don't really want to use it in your next batch unless you are making batches fairly quickly, and you are washing the yeast. Washing refers to the process of separating the good yeast from the other junk that lees is made of. It's easier to just make yeast starters (like you did) from new packets of yeast in a small sample of your wine/mead. The lees is pretty useless as nutrients for the next batch. It's mostly (in mead) just proteins that the yeast cant do anything with anyway, and dead yeast. It doesn't contain nitrogen or any of the other nutrients which are important for propagating healthy happy yeast. You would still have to make a starter with it even if you were washing the yeast. I think the only thing you really did that wasn't right was that you used too much honey. Fermaid k isn't really necessary either. Lots of people add raisins for nutrients. I just prefer Fermaid k. It seems like it would be a more complete nutrient source than raisins.
