I would watch him carefully. Some greys go off one part of the diet for a week or two, for no apparent reason (they can be very finickity), but sometimes going off the seed part of the diet can indicate a digestive upset or other disease. I also recommend that seeds do not make up the majority of the diet - it should be seen more as a treat than a major food group. One of the complete pelleted diets would make a good base (60% of the diet), with fresh fruit and dark green/orange veggies making up the rest. Stay away from avocado, caffeine, chocolate, salt and parsley. Lettuce is a natural laxative, so large amounts can cause diarrhoea.
If you are worried, it might be better to take him for a checkup at an avian veterinarian.
