Session Ale Carbonation question

Is the low alcohol in a session ale, mine is at 3%, something that could cause it to be difficult or carbonate. I have followed my regular carbonation schedule and it has produced a very flat beer. I normally leave my beers at 25-30psi for two days in my kegerater and then drop the pressure to 10 psi and bleed the pressure. This always gives me a good carbonation. What do you all think?

My seesion ale that I made is a pumpkin spice ale if that matters.
