They'll be fine, it doesn't start to matter until buds start to form n swell. At least in my experiences.

to be safe i'd go ahead and keep that humidity down anyways. Powdery mildew can form even in your veg room if youre not careful...

You are fine for now. Look up VPD (vapour pressure deficit) and you will gain more understanding. Lower humidities actually impede growth. Unfortunately, the nature of the plants you are growing mean that humidity must be dropped below optimal levels during flower to prevent mould.

One more thing. Carbon filters become less effective at higher humidities. At 75% rH it's probably only about 50% effective. 85% and it's useless. Also, check your guage. they are notoriously bad (look up the wet salt method)
