You have very high light intensity, which requires that you provide the plants with adequate nutrients to grow at the speed that the light is driving them to do. That means dosing nitrates, phosphates and potassium, plus trace elements. And, you need pressurized CO2 to be able to provide enough carbon for the plants. The other alternative is to reduce the light down to 54 watts, raise the fixture a few inches, and run the tank as a non-CO2, low light tank.

Your amount of yeast is too high. It is basically eating up the sugar quickly, which produces a lot of co2 initially and has nothing left to consume in a few days. Start out with 1/4 teaspoon of yeast and go up gradually up to 1 teaspoon. I use a little under 1/2 teaspoon to get a nice rate for about 10 - 12 days.
