Lithe printing....

Developing 6400 ilford hp5....

''Ive already failed at this''
I accidentally exposed half of the roll in one camera at 1600, and exposed the rest at 6400 in another camera.
I made a mix of rodinal at 1:100 ''let sit 10min before use'' and agitated for 1min while at 21 centigrade,
agitated again at the 1 hour point, Then just before washing and fixing I agitated for about 5min,
Results, The 1600 images came out fairly bang on, But the 6400s were VERRY pail.
What should I have done other than not shoot at 6400,
I got my recipe from a form where it had apparently worked ok for 6400 HP5.

Il summarise some of the above, Can i use wolfeganag or rodinal to develop a Lithe print on foma 123 or 312
