First timer, when to reduce humidity during flower?

[tallboy2023]

I'm about 9 days into flower. I have temp and humidity around 73 degrees and 59% RH during the day with a VPD around 1.19. It's at 65 degrees and 58% RH and a VPD around .9 at night. Pretty much same as veg. When do I need to reduce humidity? She's just throwing out pistils and stretching at this point, but seems healthy.

Your ladies look happy and healthy @tallboy2023

You can reduce your humidity anytime now, try for around 45-50% range for now.

Stay safe, and grow well my friend,
