outdoor plants

hi there i have 2 girls outdoors mango kush one is a indica the other is a sativa the front bushy one they started to flower well show white hairs about 3 weeks ago i just wanted to no how long do use think till pull time also will they get much bigger the fence behind them are 6 foot tall and i dont want them growing over that fence line lol is there anything i can use to stop streaching and get them to start budding more atm im using house and garden and dutch master gold for flower any help would be wikked

I dont think they will strech much more. But im still learning myself. sativas i have noticed strech more in the first 3 to 5 weeks of flowering then stop.
But im flowering vanilla kush out at the moment and it didnt stech that much at all then again it is indica. anyways they look great keep up the
good work going to be some poundage there.
