Liquid Culture

If the mycelium turns pinkish in a liquid culture does that mean its fucked up? Contaminated? What causes the pinkish color?

Yes, anything but white is contamination. Check out the contamination section at shroomery as well consider looking up teks that use h2o2 as the main form of disinfection and sterilization. I would probably get it away from the rest of your stuff if you want to keep it cause sometimes it can overcome certain contams. Hope I helped.
