If you are using synthetic nutrients you need to flush. Especially with advanced nutrients unless you are using their organic line you need to flush.
And it's flushing and finishing up. As it dries that's when you'll get your real smell out of it.
I notice that too. Sometimes smells are stronger and sometimes its really sticky and then it's not as sticky.
Once you finish her off she'll be grand.
And ye. That's OK. I've had higher readings and just give it a water a few hours before you harvest to prolong the drying time.
As cool as you can get it and hang dry it whole.
Most places at this time of year you'll be lucky to have a space in 20C so as low as you can get it but try not to dry in 25c or above.
Good luck.
