First liquid culture. I've left it for 2 weeks and these spots formed on top. Are they new mycelium growing or contamination? #3

My first LC I used 3cc of it to inoculate some grain. Then it turned kinda brown. I've left it alone for 2 weeks and these spots formed on top. New mycelium growing or contamination? Shroomok: Check it in 3-5 days. If mycelium on the top turned blue/green/pink/any other color, then 100% mold Healthy mushroom mycelium also might grow on top. It seems like myc to me : I'll keep an eye on it. This channel is awesome! So glad I found it. ʂƙı℘ɬཞı℘℘ıŋ: Mycelium will grow on top if LC not stirred for a long time : I don't have a stir plate. I put a marble in when I made it. I didn't stir it though until I used it, then it kinda turned brown until the spots formed. So in a few days if it stays white and it is mycelium can I just put it in the refrigerator to store for awhile? Shroomok: Stir LC every 2-3 days if stored in room temp Stir every 1-2 weeks if stored in the refrigerator Yep, marble inside helps to break a jellyfish
