That looks like normal pigment IMO....a lot of Bettas have white tips on the ventral fins and since he is otherwise acting okay-I think he is just coloring up for you......lovely fella by the way

Usually white at the tips means growth... I think it looks normal. As for water changes in your tank. maybe go for one 50% AND one 25% a week. It's better for anything under 5 gallons.
