Should i force flowering?

Hey, this is my second outdoor grow and im growing 3 jack harrer, 2 purple kush (had them ina closet but it didnt have very good ventilation so put them outside) and i have 1 plant that is texada timewarp, very dense bushy plant, it has already gone into flower, but for my jack harrer and purple kush it just seems like they are still growing! my jakc harrer are extremely healthy and are about 5 and half feet tall, i see a few white pistols down the stem abit but nothing to drastic looking, im in the north so time is of the essence for flowering considerin end of the year gets pretty moldy out, so should i wait and see if they flower on their own or should i force it? and if i was to force it how would i go about that? any special techniques?
any help would be great thanks.

I dont see why you couldnt treat your outdoor grow like an indoor one (choosing when to flower). Just like you could choose what nutes your outdoor plant recieves (in some cases depending on setup). I'm not sure exactly how you are planning on forcing them into flowering, that I would like to know more about. Hope all goes well. Happy Growing!

I heard covering them with a bag to make up for the extra dark hours will kick em over but im not sure how healthy that is when its blazing hot outside

You could probably just put them in a dark room indoors for 12 hours at a time every day to induce the flowering, then you can probably let them flower and leave them outside. I'm not to sure but it seems like it would work i never grown outside before but i would love to if i could. The few white hairs you see down the stem are pre flowers letting you know that plant is female.

Do you have any pictures of them?

Yes i got a few pics, not super recent, ill get some better ones soon, sorta hard to move these ones because they are not around my house and are currently almost 6 feet tall, the jack harrer that is,
but heres a pic of one of my jack harrer and my interesting bushy texada timewarp!

My jack harrer, nitrogen hungry, growing beast! it doesnt look huge in this pic but it is, almost 6 feet tall! this pic is older and it is just a wilty due to bein thirsty but overall very healthy!
