I can't get FB harmala to  crash out of EA with freezer temps. Are you sure that white precipitation is harmala? And I've never seen harmala crash out of EA upon cooling unless there is an ideal saturation ratio criteria I'm not meeting.

Interestingly, the EA turned from yellow to red upon freezing it overnight. I would like to know the chemical reaction happening there.

Ive been experimenting with clean up steps since i dont have ammonia available. Sodium carbonate washes dont seem to clean it up. I've alos learnt Harmala is also soluble in iso and MEK.
