Hi Skid......LOL
Go back thru and look how short the plants were after 1 months veg period.........I think all the plants grew 3x-4x that height in flowering, which lasted a full month (stretch)!!! Your issue will be height, not width- they don't grow wide but about 1/2 the plants will get to 5 ft tall and the other half to around 6 ft- it's the sativa influence for sure. EDIT: I wanted to mention 1 pheno, that was very broad and different from the rest- Xmas tree design. I have at least 3-4 of these in the room of 23 plants.
If I was to grow them again, I would pinch them all once about 5 days before flowering, and would have staked them all in some manner early on in flowering. Other than that, my fertilizer schedule has been on the lower end not going above 850 ppm and with no need too. They like their cal/mag, and I give 8-10ml per gallon in every watering- if not, they will taco a bit.
Other than that, be prepared as they are quite stinky. I've identified the smell which leans heavily to a Gorilla Glue #4 stink. Grow it and you'll know it. LOL 3 weeks left tomorrow (7 weeks flowering done) although I do see some plants that should be done around week 9 as most the hairs have already turned and the swelling has begun.
So, in a small tent, flower early!!!!!!!!!!!!! This is not an ideal strain for tent growing, too much sativa in it IMO. And as it's only your 2nd grow, you may be challenged a bit. I'm on RIU a lot and always available to help with questions, etc.
