Pink oyster problems

Happy Sunday all, I'm having some issues with my pink oyster sawdust bags and could use some advice. They seem to have colonized half way and stopped. The mycelium at this equator is very thick. The formulas are a little bit varied, but they are composed of mixed sawdust, oat bran, and gypsum. I've tried to keep the incubation temps between 80-85, and they have been exposed to indirect sunlight the entire time. Does this mean my bags are all contaminated?
These three bags show a little mycelium growth on the bottom but it is very faint. I don't see any growth on the bottoms of the others really. Inoculated on 9/5.

This bag also has some weird coloring along the side, does that look like contamination? Inoculated 8/30

In this last bag, you can see the beefed up line of mycelium a little better. There are also pins starting to form on the top. inoculated 8/30

How did you prep the bags? What was your method of inoculation? Do they smell bad?

The sawdust, bran, and gypsum was all mixed with water then pressure cooked at 15psi for 90 minutes. I should have mentioned in the first post that the three bags on top were inoculated in my SAB, while the other 2 were not as I was still getting my method down, so it's likely they are contamed. The bags were folded down with wooden clothes pins in the PC then allowed to cool. The bags were opened and one quart of spawn was added to each making the ratio roughly 1-7 spawn-substrate. Let me go see about the smell...

Pinks have very wispy mycelium. I haven't done these on sawdust, but on straw, they really don't even look fully colonized before they start to pin (mine anyway).
I think I just read the other day about some pinks on sawdust that had an underwhelming flush. I'll see if I can find it.

Also, pink oyster myc can turn pink if you let it overcolonize. That might be the discoloration, although it's hard to tell.
Also, considering the heat of the myc as it begins to colonize the substrate, 80-85 might be too warm. The core temperature of the block can be higher than the ambient room temperature.

I didn't have much luck with pinks on sawdust, but then again, I didn't supplement. The ones I had on straw did really well.

Pinks take about 7-14 days to pinning on straw depending on inoculation rates. About 4 times as long with sawdust. Probably something to do with the lignin I suppose.

Would supplementing help with the pinning/colonization times?

I don't think supplementing would help with colonization time, but I believe that your yields would be much better.

Thanks for all the input. Unfortunately I have a gluten allergy so I don't want to mess with wheat straw, and I haven't been able to find an oat straw supplier. I read something about using peanut hulls and was thinking of going to a few local restaurants that serve peanuts as an appetizer to collect waste and see how that goes. I have put 2 bags into fruiting. I did not notice a bad smell so i think they're okay. probably a little too warm, and I'm thinking too dry also. Actually, could they have possibly gotten way so hot in the core that it halted colonization? Anyway, I made 4 x shaped cuts on each bag, but the pins didn't go for the holes. I cut the plastic to save the best cluster and it way more than doubled in size over night, however, the tops of the caps are brownish. Too dry? Or could that be a pesky contam just hitching a ride? here's a few pics


So pink mycelium during colonization means they are actually over colonized? I'm still working out a bunch of kinks, thanks for all the help everyone.

The brownish color is perfectly natural. I had the same question when I first tried pinks. Many times, as they grow, much of the brown will fade away.
