Is my jumping technique okay?

I have recently bought a full sus after doing jumps perfectly for almost 2 years on a hardtail. Not on this jump, but I am constantly going nose heavy on nearly every jump and have no clue why. My technique feels okay, I'm getting the right speed and the jumps I am riding are well built. Could it me my suspension setup like not enough/too much air or too fast/slow rebound or is my technique just terrible.
