Is it okay?

[hooked on smoke]

Hi,
I started two new hot sauces. It's been in a 3.5% brine for 4 weeks today. I checked on them today and the mango habenero one had a layer of white stuff on top. Is it mold and did i mess this up?
I have been trying to learn to control the heat level and was hoping this round would be a good blend. I hope i didn't ruin this.
Asking for advice from the experts.

Best regards,

It's called kahm yeast. not harmful, but can affect the flavor. To prevent-sanitize all equipment, use an airtight airlock, make sure all fruit/veggies are submerged, use at least 2% salt brine. Also ensure adequate fermentation for acid production. Others may know more and can share.
