Even a hydromel with a SG of ~1.055 really only needs an up front nutrient addition. My last two were done that way and I had them bottled in 2 weeks.
Having said that, I actually just started my first two (separate) gallons of cider last week. I threw in a 1/2tsp of fermaid O when I pitched my yeast. When I left for vacation a couple days later they were fermenting right along with no off smells or anything. I’m hoping they will be ready to bottle this weekend. I will report back when I get home and settled and check them out.
