Anyone Ever Corrected Drug Use Info After QC?

I’m a civilian applicant for a line officer board and I realized I made a mistake on my application regarding prior marijuana use. I misunderstood the question at the time and did not realize it was asking about lifetime use.

My packet already passed QC and is headed toward the board, but I want to correct it proactively before things go any further. I have not sworn in or contracted yet.

The issue is I cannot get ahold of my recruiter right now and I’m stressing a bit about the timing. Has anyone dealt with correcting something like this after QC but before selection/commissioning? What was the process like?

I’m trying to do the right thing and update it before it becomes a bigger issue later during security clearance/poly/background stuff.
