I believe that is p.m. need more airflow and/or less moisture (r.h.). Don’t let stuff be wet outside overnight, water in morning only. Defoliate dens spots of leaves and ~all big fan leaves in middle of plant that is hindering airflow. Some people spray stuff, I wouldn’t that late. Cover top of pot if very moist.

I’m noob and probably wrong about all that.
