Hello. New to all of this. These are brf cakes that showed no signs of contamination during colonization. I dunked them and set them in SGFC. many of them developed this light to dark blue discoloration on them. Some even have a yellowish tinge as well. They all have been producing and the fruits look fine. Im wondering if this is bruising or contamination. There is a faint mycelium smell from cakes not sure if its normal or not normal smell.
