My main concern is the acid addition. Going forward save that for the end of aging. Acid is not needed most of the time in meadmaking, and, it can in fact cause your fermentation to stall.
My advice would be to get a pH meter or failing that to get some pH strips at your local LHBS or online LHBS. If your reading comes out lower than 3.3 you'll want to buffer with some K-Bicarbonate and bring it up to a happy yeast pH of about 3.6 or higher.
I think the recipe looks good. I'm including the comments below for your consideration in future batches.
I did not see articulated in your recipe. Rehydration of active dry yeast in warm water at the temperature called out in the spec on the package is critical for maximum viability. A large percentage of cells die if rehydration is done at cooler or warmer temperatures, resulting in a significant loss of activity. After rehydration, the yeast should be added to the must within 20-30 minutes, failing that a sugar source should be added to the culture. Without the sugar source cells will devolve into a premature decline phase, resulting in an inoculum of low cell concentration.
Temperature shock is to be avoided at all costs (no more than 5 - 7ºC differential between culture and must temperature). Temperature shock will kill-off large numbers of cells. For example, adding a yeast culture at 104ºF/40ºC to a must at 60ºF/15ºC kills about half the cell population
I'm not a big fan of large nutrient additions up front that have a lot of DAP (Diammonium Phospate) like the generic yeast nutrient you used. This can actually cause your yeast to stall out and then you're in a world of hurt.
Ammonia is consumed preferentially by yeast to FAN (Free Amino Nitrogen) amino acids. So it's important to bear in mind the timing of nutrient additions is. It's been my experience speaking with both wine and meadmakers that a large addition of DAP at the beginning of fermentation may delay or inhibit the uptake of amino acids. Multiple additions of multiple sources are preferred. My very basic addition schedule is dosage at the end of the lag phase, again at the 1/3 sugar break and again at the 2/3 sugar break. But, I seldom follow this course exactly and I let the ferment and the type of mead I'm making dictate the additions. This is something that I've learned from experience rather than out of a book so it will be different for virtually every batch I make.
First addition should be a nutrient mix (my preference is for Fermaid K, followed by DAP in a 7:3 ratio) Adding nutrient supplements all at once can lead to a fermentation that is too rapid, and an imbalance in uptake and usage of nitrogen compounds.
Supplements added too late (after mid-fermentation) may not be used by the yeasts, in part because the alcohol prevents their update. For the same reason, adding nutrients to a stuck fermentation seldom does any good at all.
Anyhow, I think I would take your recipe and "Oskaarize" it as follows:
Sweet Traditional Mead:
6 quarts raw local honey (Mesquite, Sage or Orange Blossom)
3 1/2 gallons water (bottled from the store)
16-20g Lavlin ICV D-47 (Rehydrated as per manufacturer's spec in Go-FERM)
Mix the honey must to a starting gravity of 1.130 (if you don't have a hydrometer, get one, it is one of the single most important tools you'll need in your arsenal)
Exclude the 8 teaspoons yeast nutrient (get out of the habit of using teaspoons to measure where grams should be used)
Exclude the 8 teaspoons acid blend (see above)
Add your first dose of nutrient (a mixture of 3.5g Fermaid-K and 2.5 g DAP) to the must at the end of the lag phase. Stir slowly so as not to release the gas in the liquid too rapidly and cause a geyser of mead.
The end of the lag phase is when you see visible foaming at the top of the fermentation vessel.
Aerate twice daily through the first 4 days of the fermentation.
At the 1/3 sugar break, dose the must with 5 grams of Fermaid-K, seal the fermenter with an airlock and then swirl the fermenter daily to keep the yeast in suspention.
