Nothing to really worry about.
Maybe it's this particular plant having issues with high N levels in soil, seen that before. Usually it's good to water her a bit less frequently and with clean water, nothing more, for a couple weeks.
Also I would increase the airflow, might be a case of low humidity or similarly related to VPD out of range.
She will go on without major issues, Last time I had a plant doing this she turned out stellar in full flower.
