Adjusting front door butt hinges with elongated adjustment slots

[thesheep]

So my composite front door is sagging a few mm and catching on the bottom edge of the door on the lock side.

I have these type of hinges that have elongated vertical and horizontal slots. 3 hinges, all the same.

My thinking is to slacken all 4 screws half a turn on the top and bottom hinges only, while the door is partially closed. Then try to force a 2mm shim under the door at the lock side to push it up a bit, then re-tighten.

Is this a good approach? Should I only do one hinge at a time? Or slacken all 12 screws at once?

That's a sound approach ( unless you have a door lifter lol )in my opinion. Only thing I'd do extra is put a view pencil lines on frame and sash so you have a datum point if all goes horribly wrong

If it’s catching bottom the it needs moving over at top , not lifting. You would need to remove screws in vertical slots as they will prevent lateral movement ( Top and middle hinges), loosen only at bottom hinge if only slight movement required.
