I have a RO/DI system for making my water. When I mix I usually mix the salt in until the salinity is 1.026 and then check and adjust the ph to about 8.3. My question is: considering that adjusting ph can effect alkalinity, would it be better to adjust the ph first, then mix the salt and check the ph?

Because RO water has no buffer capacity you won't be able to adjust the pH first.
Why do you need to adjust the pH? The salt mix should have the buffers already in it to maintain a stable pH.
In the 15 years I have kept a salt water tank, I have never adjusted the pH of my freshly mixed salt water, old water either for that matter.

How far below 8.3? How are you measuring the pH? A pH of about 8 to about 8.4 is good for salt water. You shouldn't need to adjust it up in freshly made salt water unless it is really low which shouldn't happen in quality salt mixes. pH also changes depending on aeration and whether the lights are on or off as well as other parameters in the tank.
