Question about nutrient additions

Just a quick question about nutrient additions. I found this recipe for an Oaked Blueberry Mead here, and it calls for 4.5 grams of Fermaid-K and 4.5 grams of DAP, and after each says "2 additions." The poster of this recipe, Missing, is, well...missing.

In the humble opinions of those who know more than me, is that 4.5 grams split between 2 additions, or 2 additions of 4.5 grams each?

Thanks in advance!

Check out the Mead makings Faq's https://www.homebrewtalk.com/f30/sticky-mead-making-faqs-83030/ and in particular http://home.comcast.net/~mzapx1/FAQ/SNAddition.pdf

Also from the links in the FAQ, I highly recommend hightest's spreadsheet, it works fine for me in openoffice and it will adjust the schedule depending on your recipe.

Thanks guys! The SNF pdf was very helpful. Looks like the creator of the pdf did one addition of 4.5 grams, followed by one of 2.8, and one of 1.8, so basically, to fit it into my above question, 9 grams overall of each addition split over two (or three per the pdf) additions.

Great! Gonna get this one going as soon as I can get to my carboys!
