no thats not too good, in flowering yu need it to be atleast 40% - 45% max
having humidity higher then 45% in flowering can cause powered mildew or mould

seems a bit too high for me. You better get a dehumidifier or move a lot of air so you don't develop any powdery mildew issues. try to bring it down to 40-55%

That's high, and it's only 1 week in. Needs to be about 30% lower, and then about 40% lower the last couple weeks.

.......................................................put a tray of cat litter in your tent/area and watch your humidity fall

An exchange of air via exhaust would be ideal.

when does it hit 75%.........at night? if so, place a seedling mat in tent to maintain day temps, and avoid spike in humidity. Dalton's Law of Partial Pressures, or some shit like that............

getting a fan to blow the moisture out will help somewhat.

Bear in mind your carbon filter will only be working at about 25% efficiency at 75% humidity.
Also bear in mind that humidity meters are notoriously dodgy. I have 2 that I calibrate myself (using the damp salt method, look it up) and they still often read 10% apart.
