24dc/1000mA adapter -> 1000mA Driver -> 6 x 4 Vf LEDs?
No need resister?

There is no need for any resistor, the led driver will take care of regulating the current.
you need to read the specs of the driver, if I'm not wrong you need a min of +2V higher than the total voltage drop across all the LEDS. If the total voltage drop of the LEDs are 24V then your power supply need to be at least 26V.
Then you need to consider the loading capacity of your power supply. If 6 LEDs draw 1A at 4V. Then you need a min of 1A x 6x4V = 24Watts.
Consider the quality of the power supply you are using, its advisable to use at least double the current rating so 50watts. I personally have burned so called "100watts" power supply with only 40watts of loading.
Try to use thicker wires to prevent excessive heating of the wire from the driver to the leds and always connect your leds in series.
I normally buy a bigger power supply to drive 2 led drivers with 12 LEDs.
