stalled at 1080, what was your OG and the starting PH?
i did a few side by side comparisons with trub, dunder, with and without oyster shells.
i found the combination of trub and dunder to be both acidic and dropped the starting PH of the wash to a bad start of PH 4.3
then the wash dropped to PH 4 before recovering slightly and luckily fermenting out.
in it's side by side, the addition of chicken grit/oyster at the beginning raised the PH from 4.3 to 5.2 in 24 hours.
BTW i use almost the exact same recipe as yours.
early days, i found with generations the ferments got harder and harder, i think it was all PH related.
adding more and more chemicals, more and more yeast to stalled washes just didn't work.
i ended up splitting my last stalled wash and managed to coax it over the line.
since adding chicken grit to the washes, all my PH problems seem to be solved (and the comparisons back that up)
i'm not sure that adding chicken grit will help at your stage, but i might try it.
or split the wash, add appropriate amounts of sugar/molasses and get some chicken grit from the pet store.
hang it in a hop bag.
good luck
