How many laps are you performing on the 12K? Should be more than 50.
I use 100 laps. Also, have you refreshed the surface of the hone before lapping? When I lightly lap my 12K just before honing it...

I should also add that my hones are stored in water most of the time but not all the time. Currently they have been dry an unused for about the past 2-3 months. When I start honing again after Xmas...

My Norton hones are single grit hones so I do not need to be careful of any bond between 2 stones. I would not store a 2 grit hone in water. So far I have not seen or felt any change in the Norton...

I used to leave my water "pond" without a cover. Wow! the stuff that was floating on the surafce was very surprising.

Probably the last question I have is how many roundtrip laps are you performing on the CH12K? and what grit hone are you using before that?

I always go from a Norton 8K to the CH12K. I usually...

I believe that the DMT 1200 leaves deeper scratch marks than a 1000 grit sandpaper or other stone. So if you follow the DMT 1200 with a 1000 grit sandpaper/stone then the scratch marks will be...

I have always stored my single grit Norton's. Ch12K and other stones in water for several months at a time with no ill effect

I do take issue, as always, with using a 1200 diamond grit to set a...

The problem is that you lapped it with the DMT and nothing finer after that. Doing so will result in a "grabby" surface texture. No matter what I use to flatten a hone I then always use a finer set...
