These dark spots on the leaves just showed up the past couple days. Check out the last photo for a closeup. What should I do?

Thanks

Sounds like you plan on harvest soon despite they would deserve few more weeks. You flush? That last foto looks suspicious for rot…
 
I haven't flushed.. I have it in a 5 gallon SIP system and haven't put in nutes since about 10 gallons of water ago. Can you tell me more about rot? Can it be prevented? What causes it? etc..

Bud rot is botrytis. It’s a fungus that will attack and destroy your buds. I‘m not sure if that one is bud rot or not but I get why he wonders. In general you prevent it by avoiding high humidity during flower. You want to keep the humidity at 50% or less in your grow room and get good air circulation. That means you want a hygrometer to test humidity, fans to keep air circulating and possibly a dehumidifier. If you look at any of the popular websites on growing weed there are lots of articles explaining what it is, how to prevent it, and what to do if you find it.

Three rules of life btw
1. don‘t eat the yellow snow
2. don‘t take the brown acid
3. DON’T SMOKE BUD WITH ROT

1 and 3 are mandatory 2 is discretionary

Well I have never grown SIP so can not tell you if yours not adding nutrients caused plant look like overall defficient but it would make sense. There are leaves in the centre of the 7th foto you have posted. Their necrosis is typical sign of mold or bud rot. Thats ussually because of high humidity and poor air circulation combined with density of the buds later in flower…
 
My humidity measured at 44%. I moved my fan to below the plant and have it blowing upward. I've also increased the speed of the exhaust fan.

The only thing I've done different this grow is I'm venting the exhaust outside. I'm wondering if there's some type of build up during the dark period of outdoor air causing moisture since the blower isn't running..

why wouldn’t you run your fans 24/7? If air isn’t circulating you can get pockets of moisture especially if your canopy is dense and you don‘t defoliate. 44% should give you zero problem with bud rot.
