Is it possible for less than specify bright nickel thickness on parts to cause chrome misplate? (for example nickel spec. is 25 µm , actual nickel thickness 18 µm .)

No, I don't think that's the problem. Plate a Hull cell panel with 18 microns (or less) of nickel, then plate it with your chromium solution and tell us what happened.

The lesser thickness is not the problem. Look for something else..!

I would look at inproper activation or excessive brightener.James Watts

Adding to previous responses, the same reason that caused the thin nickel could be causing the chrome misplate as chrome has less throwing power. So, I would look for anode placement, part geometry, time in bath, voltages, etc. By the way, you didn't mention the substrate.Guillermo Marrufo
