Is this normal or possible infection?

I’m still new to this and I get paranoid during the fermentation.
Is this the Krausen starting to die down or beginning of infection. It’s only been fermenting 3 days or so.

Put that fermenter where you can't see it and leave it for 2 weeks. It is nearly impossible to get an infection in primary that hasn't been opened provided you had it sanitized before you added the wort. Bacteria don't reproduce very well in the acid wort, then you added several billions of yeast cells that quickly produced CO2 and that also inhibits the bacterial reproduction. Soon after that the yeast added alcohol.
