Al your fish are on track ! 64 F is right to start the spawn and photoperiod is right at your location. Here is a bit from SARC

Largemouth bass in the South
will usually spawn when 1 year
old, if they are at least 10 inches
long. Males select a nest site in
the spring after the water temperature
has stabilized above 60o F.
Bass normally spawn at temperatures
of 65 to 75oF in water
depths of 1 to 4 feet near shore,
but nesting has been observed as
deep as 20 feet in clear water.
There are some data, based on
induced spawning trials, that
indicate spawning is also affected
by photoperiod or day length.
