I'm not 100% sure of its default, but I know coir and grain are 5.5-6.8, below 7.
Increasing the pH to say 7.5-8 will lower chances of germination.
I am working with spores, so I went with pH 6.5.

I like pH 7.5-8.5 for "live" oyster substrates, from reading cubensis is no different. You don't want spores after you have live mycelium.

I had better mention the down side to lime, lime can become soluble, although only instantly when it reacts, and else it's slow to react (over time).
While the higher pH deters spore germination, it also adds a soluble carbon source, which acts like a very weak soluble sugar.
I been successful with germinating spores using calcium carbonate (soluble end product), so it's not foolproof.
However, it should be no cause for concern on 100% cellulose, some concern with wood.
The lime causes decay of acids, which in turn can produce more solubles.
9 times out of 10, you will be successful with using lime.

Yes CaCO3 water, or wood ash water, will trigger pinning with almost all types. I'm not 100% sure what causes it, here are a few reasons:
Reaction to sudden pH changes, sudden change in carbon-to-nitrogen ratios (soluble carbon) and decay of materials via pH.
Wood ash its self adds elemental "oxides", mycelium love oxides and O2 in general, they use it to decay matter.
All of this adds up to, either singularly or in combination with water, "I need to fruit" or "I am happy".
Pleurotus nebrodensis, will fruit specifically from limestone (CaCO3) rocks, yes rocks.
CaCO3 (inorganic), is also used by animals, to make eggs, or shells.

I don't think it matters, there is variation but they all contain CaO which converts to CaCO3.
