I don't have the full table but here is some info. Every upgrade increases the size of the nutrition centre with 5 players. Each upgrade is a 50k investment cost and it will increase the maintenance costs as well.

To piggyback on that response, a level 2 nutriton centre can help 10 players at a time and maintenance is $18,000 per week.
