Wait, cease and desist!
Are you only having a problem on this one note, first fret on the high E? (hmm, guess it must be a guitar...)
If this is the only place you're having a problem, then don't mess with the truss rod(s). Someday you should learn how, but not to address a problem of this sort.
If the problem is limited to the high string, and the first few frets, then you should start by raising the nut very slightly on that side.
Another possibility is that you have a very localized fret problem, like maybe the second fret is just a touch high under that string. This is a little harder to figure out, but if you like the way everything else plays/sounds, then experiment a little more in the first few frets on the high strings, and tell us what you find, before you go changing big stuff.

Actually, if the problem is really only with playing the F at the first fret, then it almost certainly isn't a nut height issue either (could be if it was at the 2nd or 3rd or so), so maybe you don't want to mess with that right away either.
First figure out whether it's just the F, or maybe also the F#, G, etc. If it's the first few frets, then try raising the nut, though it still probably won't help with the F. If it really is only the F, then as an experiment try raising the bridge a little on that side to see if it helps. In that case, I think you'd want to look at the next fret or two as a better long term solution.
You might also pay careful attention to exactly how you finger that note - are you perhaps pulling back on the neck with a little more pressure than you would elsewhere?
