It is "rolled in the bud" and that is the only ID characteristic I can see from looking at that photo. Most commonly 'up north' that is an annual rye (would go to seed and then die out in hot summer weather--I doubt it is an annual Rye) OR a Tall Fescue. There may be some other choices down south that I am unaware of having never lived or worked there. KEY ID feature of all TALL FESCUES is a serrated blade edge that will bite at your skin when you stroke your fingers down the blade edges from TOP to BOTTOM. You can also see this with a 10X hand lens. Tall fescues are considered transition zone grasses and grow best from southern PA through the Virginias to (perhaps) the Carolinas. Further north or south I'd expect it to be called a weed as it does not like those weather extremes. In northern turf it can be either a desired turfgrass or a weed. More common varieties are very wide-bladed and can stick out when mixed with Bluegrasses, Rygrasses or other (fine bladed) fescues. My backyard has a lot of TF as I've incorporated it intentionally to help with the adverse growing conditions--southwest exposed slope (full afternoon sun), thinner soil and some sporadic shaded areas. In my front yard (100% 'Midnite' Kentucky bluegrass), any TF would be most unwelcome. Both lawns are nice. The front gets full sun, is irrigated regularly and has 8" of top soil--optimum conditions for Kentucky bluegrass.

It isn't Comfrey but it is Boraginaceae. Pretty sure it's Green Alkanet - Pentaglottis sempervirens. A common weedy escape from cultivation and a real nuisance which self seeds. Don't handle without gloves as it has irritant hairs which get stuck in your skin. The flowers would confirm if you can show them.

Nutz. Lol. That should be fine. Let's bring Lucy in because there is a little 'splaining to do: Spreader settings for a fertilizer product are based on (1) Prill size (the diameter of the little beads of the product) and (2) the percent of the controlling nutrient content in the product. (this is the highest of the three numbers, X-X-X. For most products this will be N, the first number.) Although lawn nuts shoot for one pound, in most cases this will result in less than one pound of nutrient per 1k sq ft. in most do it yourself homeowner aimed products like Scotts. They like to play safe. For instance, Scotts Turfbuilder 32-0-4, 12.5 lb. bag for 5k sq ft. = (12.5/5)X.32 will result in .8lbs of N per 1k sq ft.; or Milorganite 5-2-0, 36 lb bag for 2.5K sq ft = (36/2.5)X.05 will result in .72 lbs of N per 1k sq ft. Moving on. Prill size. Most products come in a standard prill size. You need to determine if the prill size of the triple 12 is the same as the Scotts or JG. Take a palm full of the triple 12 and a palm full of the Scotts or the JG and compare. Keep in mind that due to the manufacturing process, there will be some prills slightly smaller than the majority and some larger. If prills of the triple 12 are very similar, proceed on. % nutrient. Determine the amount of triple 12 nutrient that will be applied when using the Scotts or JG product spreader setting. As an example, using Scotts Step 3, Scotts recomends using the 3.5 setting for the Scotts Edgeguard spreader and the 12.5 lb bag will cover 5000 sq ft, so...12.5/5 = 2.5 lbs of product will be spread over 1k sq ft at a 3.5 setting. For triple 12 (if prill size is the same) that means using a setting of 3.5 will result in 2.5X.12=.3lbs of N and P and K being applied to to 1k sq ft of lawn. At the 3.5 setting you will need to make three passes to apply .9lbs/sq ft of N, P and K---about as close to the 1lb of NPK as you are going to get. HOWEVER, as you are applying the triple for the purpose of applying Pand K for root growth and as root growth is maximized when soil temps are 55 to 65F AND as P binds very quickly and its availability is thereby reduced, you may want to divide the three apps and spread them out over the month of October for maximum benefit. WARNING: The fact that a setting of 3.5 results in 2.5 lbs of product does NOT mean that a setting of 7 will result in the application of 5lbs of product. There are are number of methods to calibrate your spreader: Google "spreader calibration". Too much work and/or mess for me though.

Not pokeweed; it looks like a cherry tree that arrived there via bird poop. A closer picture would get a definite id - I'm just guessing that because I pull up jillions of cherry seedlings every year, and the ones I miss look just like yours after a couple of years.
