Hi everyone, I did my first G2G transfer last week (cubensis, Jack Frost) and everything seemed well. This morning I decided to do a shake and break because the jars were colonizing really well and were colonized about 30-40%. (Picture 4)

Now, 5 hours later, I went to check the jars and the grains seemed blue/green, definitely a color I haven't seen in my jars before. In my opinion it definitely seems contaminated, but I think it's weird this color wasn't present before the shake and break. The mycelium was growing well but it was hard to break it up in the jar (I thought maybe because the transfered grains were over-colonized). As far as I know the mycelium won't bruise blue like the mushrooms do?

All my jars now have this strange color. Is this contamination or should I wait a bit longer before jumping into conclusions?

The pictures are showing the weird spot, the last picture was the jar this morning before breaking the mycelium.

Beginner here, I had 1cc of LC and no jars anymore so I thought, why not use the last cc to expand it.

I never made LC before so I just messed around a bit, I used 1/4 grain boiling water, 3/4 water and 1,8% honey.

In just 4 days the liquid culture expanded from a small blob to a jar full of mycelium, I'm really happy with the results. The color cleared up (last pic is after PCing) and the mycelium expansion is crazy.

The strain is MAK95 (can't really find a lot about it).

I honestly didn't think it would expand this fast, and I have no idea what to do with it. I have 20 jars going at the moment and this is all for personal use/friends, so maybe I should just put it in the fridge to save for later?

I'm a beginner and this is my 2nd time making bulk substrate, the coir I bought in the same store is full of fibers. The first time it was really fine ground coir, almost like peat. Should I buy a new brick of coir or will this be ok?

First picture is the new fibrous coir, the second picture is the 'regular' one

Edit: I'm growing cubensis
