My 32x32 DWC Auto LED Grow - Questions

First grow with DWC & LED and AUTO

The thing has done really well and I started late in training! It's Nirvana Bubblelicious auto. Biggest problem is heat in our garage is starting to get too hot and its near day 60 and hasn't started flowering cycle. It was suppose to auto after 3 weeks. It's getting huge for this tent! Glad I only tried one. I switched lighting to 12/12 from the 18/6 it was at. Only one day of that so far, hopefully helps give a push to shift to flowering.

My questions:
- Garage is getting to hot here, was hoping to be nearly done by now, but I'm still waiting for flowering. I can move to the walk in closet, but odor control will need to be excellent. It does have attic access above the tent. Would venting one plant really cause potential mold issues? I'm in a desert.
- Any other tips to help push this to flowering stage? I've started altering nutrients to flower cycle.

I'm worried I wont be able to keep it going if smell gets too bad in the closet. I have a children, so can't have them wondering what's the smell in the closet.

Are you certain its an auto?
I would bet not if that's 8 weeks old

I can only rely on what I purchased. It says auto fem and that is what I was suppose to receive, but now wondering if not.

Apparently your 8 week old plant is not an autoflower. It's usually obvious after 3-4 weeks.
Your switch to 12/12 should give you some answers.

This NL Auto sprouted Feb 1, 8 1/2 weeks old, has been on 18/6 from day one:

Yeah something off. Day 3 of 12:12 and here is the updated look. Does this look like preflowering?
