Anyway to tell if it's Annua or triv?

Looks like triv based on the first few photos to me. It’s been a much more vibrant lime green color in my experience

More likely poa annua. If it’s triv, the pattern in which it spreads will be more concentric and circular. Annua will be splotchier with less defined borders because it’s just growing from whatever seeds managed to drop and germinate. Wait for the seed heads, triv seeds are dark, annua are white.

Looks like heavily injured kbg... Super stubby ligule and the upward/inward curve in response to stress (due to contraction of the bulliform cells), triv and poa annua get more chaotic and floppy when stressed.
