Here's my sketch in case someone wants to look at it.
I did a check with my multimeter and the more pins at set HIGH on the shift register, the less voltage I get. Is there something I need to add to my setup to tackle that. For the moment, it's the numitrons legs straight to the shift register. I going to try to illustrate it.
//Pin to clear the register
const int clearPin = 7;
//Pin connected to latch pin (ST_CP) of 74HC595
const int latchPin = 8;
//Pin connected to clock pin (SH_CP) of 74HC595
const int clockPin = 12;
////Pin connected to Data in (DS) of 74HC595
const int dataPin = 11;

registerWrite(0, HIGH);
registerWrite(1, HIGH);
registerWrite(2, HIGH);

// This method sends bits to the shift register:
void registerOff() {
for (int i = 0; i < 8; i++) {
registerWrite(i, LOW);
delay(100);

}
/*Not mine, from tutorial*/
void registerWrite(int whichPin, int whichState) {
// the bits you want to send
byte bitsToSend0 = 0;
// write number as bits
bitWrite(bitsToSend0, whichPin, whichState);
// turn off the output so the pins don't light up
// while you're shifting bits:
digitalWrite(latchPin, LOW);
// shift the bits out
shiftOut(dataPin, clockPin, MSBFIRST, bitsToSend0);
// turn on the output so the LEDs can light up:
digitalWrite(latchPin, HIGH);

), and would be easy to write code for. The options I found so far:
