As others have said, you need to rebalance the table numbers so that the blinds are pressuring all players equally.

This is taken very seriously in "real" tourneys. For example, in a tournament where the whole final table of 9 gets paid, it is common to play "hand for hand" at the two-tables-of-five stage: a hand is dealt at each table, both are played to completion, and then another hand dealt, so that both tables play the same number of hands. This prevents one table sitting still waiting for someone from the other table to bust.

Of course that's unlikely to be needed in your tournament, but it illustrates how seriously this is taken.

Have fun with it!
