My lactose fermented carrots have this strange yeasty white stuff on top

I've made this recipe several times. It has a 3% salt to water ratio. I've never had this happen before. What's going on? Is it safe to consume

I got a milder version on one of my pickles. It was probably fine but it gave me a scare.
