I got up in the middle of the night and check my temp and RH. RH was at 75%

During the day I watch it pretty constant and it stays at around 45%. I guess at night it's been skyrocketing.
Anyways, the plants are growing well. I notice a pretty wofty smell off old water though.
Actually when I smell the flowers I smell more of the old water smell than dank.

Should I be worrying about the ROT? Some of the buds are green all around and some are a darker redish, purplish, darkish color under the white hairs. They look terrific but the smell is starting to get my imagination running.
I added a dehumidifier today. I'll give it a couple hours and then check it. The RH went down to normal after the light went on but as far as I know the spores that causer bud rot live in 50% and up RH. I hope they haven't been prevailent at night when the humidity has been going up.
Anyways, heres the pics. Let me know what ya'll think.
Input would be greatly appreciated!
#1) I tried to take a picture of the color of these buds. A few look like this. I guess it could be the light but I'm not sure that's why I'm asking.
The rest are just bud pics and a couple changes I made in the room.
