Sounds like you are of to a good start mate I cant wait to see some pictures!
I have done a bit of homework for you(with the help of a few friends) and I have got a bit more information for you, but lets get to your questions first.
Q1.can I lst her ,pinch, or just let her go,the breeders info is very vague on this matter
A1. I would recommend lst if you wanted to do anything to her, topping isn't recommended for autos, although some of them react very well to it most don't.
Q2.I plan on using no liquid nutes just teas(tlo style) and adding a layer of pure bloom when she stops growing up and flower sets in will this be sufficient enough for nutrients she seems to be not lacking anything at the moment but this is my first attempt at an auto so don't want to waste time or space
A2. your plan is a good one, I know a lot of people who use your method with great results. so don't worry
Now here is a bit more info on Vision seeds AK 49 from an private grower so there is no bias in the info. This was only the second auto grow for guy that grew them so you should see similar results.
From germinating 10 feminised seeds there were three pheno types present
1. 4 were short, best smell and production
2. 3 were tall Sativa infuence (best to me)!
3. 3 were medium sized
The yield on them was 35g dry for the smallest of the plants, so you should be aiming for that at least.
The report on the quality of the bud was:
Super stinky, so a good carbon filter is a must.
Nice, strong buzz. the sativa influenced ones were more of a cerebral buzz, excellent daytime smoke. the medium and short ones were more of a couchlock buzz, more of a night time smoke when you haven't got lots to do.
It took him 3 full months from seed to harvest, so now you have a real life time schedule to look at and plan your grow against.
And of course you need some pictures, so here you go mate
