back joe looks like you have been given alot of love to your baby,CharlieMopps this is good advice as i myself had to re-pot some from 2 gal=8" square pots to 3.5 gal=10" round pots you can get them in woodies €5 a pot easily available elsewhere too.
did you get ferts?veg/flower? if it is bio grow you have you are correct on 15ml-7ltrs maybe just a little high but not much keep it there for another week then raise it, but as you have only 1 plant only mix as much as you need you dont want to leave it sit for longer than 48hrs i believe it can go sour its what i heard and work by and has worked for me, so i suggest you mix 2 ltrs water with 4 ml B.G you could probably flip her? in a week or so. plant looks healthy so your doing well nice branching now lets hope its a girl and if i'm a bettin man and i am i'd say she is a girl keep up the good work
