120 g Tank with rocks . ammonia 0 nitrite 0 nitrates 50 ppm . I did 50% WC but still 25- 30 ppm . Planning on FOWLR should I lower nitrates ? Do WC again 25% ? . I’m using Red Sea test .

For a FOWLR tank, you can start adding fish, even with these slightly elevated levels of Nitrate. I'd still try to get them down, but generally speaking anything under 40ppm Nitrates will be ok for FOWLR.
