got some arrows fixed up for the kids' bow yesterday.
40# @ his draw (26.5")
50#-52# wood arrows cut 28"
125 gr f.p.
leftie, longbow not center shot,the nocks kick to the right after leaving the bow but they group really well. Lowered the brace height a little bit and that improved the flight some but not perfect. Raised brace height and no improvement. Any ideas what else we could change to help the flight? May try some heavier points.???

try heavier points. from a lefty I believe thats stiff
?
TRY heavier points
I think you're underspined. The nocks kick right, but the arrow impacts to the left, right?
OL Adcock Custom ACS Bows has a page on tuning longbows and recurves. His method involves a couple fletched and a couple unfletched shafts and making adjustments based on where the two groups of arrows impact the target. He doesn't address which way the nock points.
I just set a batch of arrows for each of my sons (and one for myself) using this method. My youngest is real close to your son's specs (he is even a lefty, also). Based on what I was seeing, I would guess your arrows are a little overspined. Perhaps, the tail end is slapping the rest on the way out and kicking the back end to the right.
I made my son's arrows 31" with 160gr field tips and I had to sand the shafts down to 45#. He is drawing 25.5" @ 37#. I might have too much weight in them, but they fly straight.
Good luck and give OL Adcock a good try. I will warn you that you need some lattitued in your range... I put a hole in the cabinet in my garage. Find a hill to shoot into.
