I'm pretty concerned here about my Auto blueberry. A couple days ago as I was checking my babies, I noticed a rather gross smell lingering in the tent. Over the past couple of days the leaves on my Auto blueberry have shriveled and started turning a a near blackish color. Is this mold or some kind of deficiency?
Pungent odor and dark shriveling leaves?

I would be concerned as well. I would check your bud for rot....especially if this happened over just a few days. I believe a nutrient deficiency would not be this aggressive. There are people here that know far more than me though...hope fully they will weigh in soon. Good luck!! 
Also..the odd odor part leads me to think you have something dead and rotting.

Can you give us some more information? Temperature and humidity levels inside your tent. Soil used, nutrients, strength and frequency. Also a picture of the whole plant would be helpful. Do the leaves feel dry and crispy? Also, inspect them with a magnifying glass and look for signs of mold or mildew.

Also what is your nutrient schedule like? If your new growth (emerging leaves) are crisping up right away; could be a sign of overfeeding. From the picture they look kind of burnt.
PH: 6.2
RH: Usually between 45%-60%
Soil: 3 Gallon pot; 50% ffof 50% backyard soil
Nutes: about 1/2 tbs of tiger bloom per pint of water (usually what I feed) the last couple of weeks.
I feel like I've been a little heavy on the nutes. I've been flushing for the last few days. Unfortunately I haven't been able to give the proper attention to her because of work, and have gone a bit overboard on feeding. Originally, I'd feed after two days then water water after two days. TBH, recently I've been forgeting when i feed her and when I give her straight water. IIRC The fan leaves started to droop and the stems started to turn purple. I thought the purpling was from a P deficiency, but soon the leaves started curling and they've turned a brown-yellow and are dry and crumbly.

The red stems and state of the leaves does indicate a P deficiency. It also sounds like you've been watering/feeding too often at every 2 days. Weed like to go through wet/dry cycles, so the best way to know when to water is by the weight of your pots. Get a feel for when they are almost completely dry and only water when they feel that way.
Some people like to alternate between feeds and plain water. Personally, I find it easier to just give a milder nutrient solution every feeding.
The pH of 6.2 that you listed, is that the pH of your feeds or of your run off?
OF is known to have pH issues and sometimes can be very low, as low as 4.5. If you haven't been checking your run off, you will need to. You could very well have low pH which is causing the nutrients to be locked out. Also, what is the temperature at the top of the plant? Another question, what kind of light are you using and how close to the plant is it?

Another question, what kind of light are you using and how close to the plant is it?The PH I shared was from sticking the meter into the soil. I'll post back later with a run off PH, as I'm currently unable to do so because of company. Temps are generally between 87-91 Fahrenheit.
I'm using a single 125 Watt 2700k CFL and distanced about 4 inches from the light bulb itself. I recently switched places of my Photo that's growing with my auto and have noticed an improvement, but I've also been flushing that too because I know there was a PH problem (5.1 with the meter in the soil). I've flushed my auto with water at PH of 6.8 thinking it would help, but it hasnt. I have a big bag of Lime which I'd been using to buffer my photo, should I add a tbs of that with another flush?

Hmm, that took a little longer than I wanted. Anyway, I got the run off, it measured at about 5.5 yesterday. The odor has lessened and when I pulled her out of the tent yesterday she smelled much sweeter. I guess that's good news. Day 69, she looks like hell, and I feel like I've botched my first grow. Stones slap
