Why my two liquid cultures are so different?

These are two liquid cultures which I prepared from 4% honey. Both sterilized together. But contain different strains. 1st Jar- Initially there was no visible mycelium in the jar. It was only visible after 3 days. The jar is still very clear and growth is clearly visible. Contain NC strain. 2nd Jar- It had visible mycelium strands from the beginning. But now the liquid has turned milky and mycelium growth isn't very clearly visible. It was inoculated 3 days before the first jar. Contains P Natalensis strain.

Are they fine or this is a direct sign of contamination and I should check?
