fret buzz on 5th and 6th strings during power chords?
Whenever I have a chord where it's like 577xxx..

the 6th string will buzz a lot when I hit it with a little extra force than normal or just with normal sometimes.. Don't know why, and then 5th will seemingly buzz too because my finger is to far from the fret.. I donno exactly.

Anyone else experience this?
yes, Just try Hold your fingers as close (behind, not ON) to the frets as possible, If that doesn't work It might be the action (How high the string is to the fret board)
