coir/coffee w/o lime oops

Was doing my first attempt at bulk substrate the other day and after I finished It occurred to me that I forgot an important step. A coir/coffee sub can be acidic so lime was supposed to be added. In my rush to make my bulk sub I forgot to ad lime
Anyway should I continue with these too casing and into the FC or will they be contam city by the time they make it there and yield no mushrooms worth my trouble?
It's a stupid mistake but as a total noobe to bulk subs and casing I should have thought it through more.

no lime, Gypsum is for ph control lime is to bump the ph up. I would have added gypsum too but I won't get any until march. I'm meaning that the low ph caused by having no PH adjusters in my bulk sub would possibly make a better environment for contams than mushrooms and asking what people know of this.

don't use lime in your substrates. coir is my substrate of choice and i never lime it, just gypsum.
use lime in your casing layer

well that'd be good for later but what's done now is done so do I worry or not?

Spent coffee grounds are PH balanced. No worries.

Like RR says, myc likes some acidity anyway. Because of the acidity, the myc should colonize the sub quickly and contams will be of little concern at that point. You want the casing to have a more alkaline pH because it won't be fully colonized like the sub and therefore is more suceptable to contams.

Correct. Gypsum for substrates, lime and gypsum for casinig layers. RR

I thought myc is more attracted to neutral ph and it was contams that liked acidity.

oh n/m. I had read a few posts where people argued spent coffee grounds were the same acidity as coffee but that'd put the whole post to rest here. So presuming that is correct that kills the issue.
I mean since I've got 2 people here telling me it's neutral and none of those posters are showing up to say it's acidic here. I'll have to assume it's neutral. Good news for me anyway.

Mushroom mycelium prefers a pH of around 5.5-6.5.
We don't lime casings because the mushroom mycelium 'likes' it. We lime them because contaminant molds 'hate' high pH. RR

Starbucks reports that most of the acidity is removed in the brewing process, leaving used grounds with an average PH of 6.9 and a carbon-nitrogen ration of 20-1.

I've used 100% straight coffee grounds for a bulk sub before with about a liter of rye, the colonization time was fairly fast so a P.H buffer defiantly was not needed but when preparing coffee grounds yourself in large quantities you defiantly should take a P.H reading prior to spawning as I am finding out the hard way lol, oh well...
If they've been brewed prior you should be good to go depending on the coffee grounds used, this cheap no name coffee grounds seems to increase the P.H abit to high, the mycelium is taking forever to chew through the bulk tubs my split personality keeps conjuring up when I let him out.

well the CG that I just used were my own organic fair trade good stuff, but I'm about to break into the shit brand stuff from work. If it's diluted with coir should the acidity be a problem? Or is that just from the straight coffee subs your talking about? Anyone know the acidity of spent percolated coffee grounds (they are ground bigger) if it would be different at all? I have seen the prices of ph meters and I've got no inclination to put any more money into this hobby at the moment and if I do it'll be into petri dishes and agar.
