If you cant lower the temps and the 27c stated in your diary is the temp your grow space sits at then the ideal humidity is around 57.5%,VPD of 1.12. Can you increase extraction to pull some more hot air out?. From what i understand you really dont want to be sitting that high in your RH during flowering. Im sure someone with more knowledge then myself can clarify. Good luck.

You should not flush.. You should adjust your nutrients accordingly and not oversaturate your plants.. Flushing for 2 weeks does some really negative things to your plant. It breaks down stored nutrients and causes your plant to circulate more nasties to the bud sites.. It cuts out on terpene production and makes for a quicker finish and less weight.. Flushing for a few days before harvest sure that makes sense.. 2-3 weeks is much too long and you will absolutely negatively affect your plant.

yes you should. the reason behind this is that the darkness helps the buds to ripen up a bit more before chopping and getting that nice harvest. although some say it does nothing and some say it helps, in the end it is your choice, and what is two days of darkness just to complete your grow as you have already come this far. so congratulations on the up coming harvest you did a great job. if you do decide to do the dark ness you should give them just water right before you close her off. this way the roots stay moist during this time. you are going to be one happy grower thats for sure.
