Outdoor Attempt

So I got lucky and found a seed in a batch of this nice pink lady I got from a good source. I started it out in a solo cup, then a 6 inch pot, then 10 inch pot and thats where it's at now. It's been outdoors for about 2 months now, my best guess is 50 days or so.

I'm fairly certain she is a she. I'm going to try and get some photos but for now I can only say she's about 2ft 5 inches and starting to show signs of small hairs around the top and on some side branches. They are a light yellow and orange in color. (hairs)

Question #1:
Since I have no grow room to perform a 12/12 lighting schedule, should I just leave her be until she blooms on her own naturally?

Question #2:
I'm thinking about transplanting once more and getting her fresh nutes. What would be the best nutes for the soil in a 5gallon bucket? or should i look to get something smaller?
