Hi,
I was wondering if anyone knows what programme I need to use to subtract the
Fobs of two different crystals from each other.

Presumably the two data sets are in the same spacegroup with the same
cell dimensons more or less?
You must cad the two data sets together with suitable olumn labels and
add FC PHIC FOM from some suitable set of coordinates.
Scale them to the FC or to each other - I use program SCALEIT to do this
Then use the FFT utility to do a differenc map Fobs1 -Fobs2 PHIC FOM
