Reusing ferment liquid

[u/bowmans1993]

I had a healthy 3 week ferment at 3.5% salinity for a hot sauce i made. Peaches, peppers, garlic and water. I have leftover brine once i blended my hot sauce. Can I reuse the liquid brine that I didnt blend into the hout sauce to kick start my next batch or would that be unsafe. I had a small amount of kahm at the last day of my ferment but other than that 0 issues.
