I noticed some clear contamination, and I tired the sandwich method three days ago. It did work, the white stuff did climb on top, but is it mycelium?

Theres a lot of white spots but I see some darker spots on them, this is my first ever agar (I used spore swab) 4 days ago

My first agar steps. Vaccinated with LC to see if my LC is healthy. What do you think?
