I am fairly new to FASTLED programming and am looking to make my entire LED strip blink at the same time. Similar to the Example Sketch "Blink" however all 30 of my LEDS. I might just be having a temporary mind derp right now but I cant figure it out.

For your case, you want to change the color of all LEDS, so you would call:
fill_solid(leds, NUM_OF_LEDS, CRGB::Red);
To turn them back off, you would change the color to
