Hello! I don't mean increasing your Watts, 59 will be enough for your space. Well, starting as you are (option 1
) would be better in my opinion.
As you proceed, and see trichs appearing after 2-4 weeks, it would be better to replace one of your 2.7k bulbs with an equal watt 6.5k one! Just keep in mind that autos like the mixed spectrum, I'm just sayin change 1 of your bulbs so the spectrum is more "natural" for flowering and you can finish as you are!
Also keep in mind that autos can tolerate 24/0 light and also thrive! I'm not saying you should do this, but I personally think that giving it 8 hours of sleep is too much for an auto..
What you should also consider, is that you can change your light cycle as you proceed, your lady won't get hurt at all!!
Hmm, the smell.. I haven't smelled one but considering its genetics, I would say that about 5-6 would be a Lowryder..
Don't forget, though, while making a stealthy grow, people can easily know if you have even the lightest smell!! So a gel odour destroyer or sthng, I think will do.
About the yield now.. You could harvest from 0 (if sthng goes totally wrong) to 18-20 g IMO!
May you harvest the most!!!
