Hi there
It looks like you have what is called, wet spot, its a bacteria infection caused by to much water, when the grains get a milky look to them with milky fluid in between the grains, its pretty much guaranteed to be wetspot.
the good news in cubensis mycelium can beat and eat wet spot infected grains, if they some how loose some water.
you could do a grain to grain, I would scrape the fresh mycelium from the top in a glove box with a fork and just use that in a new jar of rye grain, just avoiding getting any nasty bacterian in your new sub. Rye grain gives best results imho, I don't use anything else.
I dunno what tek you are doing .... I believe that the traditional PF Tek or rye grains > bulk sub is the most used method imho.
Ff you do a grain scrape to a new dryer sub strait you should be good.
hope this helps
much love and warmest Regards.
