Try testing the pH at the end of lights on - at the end of lights out, the pH gets depressed because everything in your tank isn't photosynthesizing, it's respiring through the night adding more CO2 to the tank depressing the pH.

Also, I'd switch your Alk supplement to sodium bicarbonate right away and see if that makes the difference for you. I suspect it will.
