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.

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............

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.
