do you have a light leak? some indicas can flower with more than 12 hours of light. depends some flower when there is 14 hours of light. so ive read. the taller looks more sativa they can take upward of 15 weeks to finish.

you have some serious heat/ventilation issues

sativas like that take way longer to finish. Looks like you may have gotten some seeds with poor pheno's or if they were clones I would sat that strain is worn out (clone from clone from clone from clone etc.) also check for light leaks and get yourself some nice hybrids.

That looks like a pure sativa to me; if it is you need to be very very patient my friend, she'll flower when she's good and ready. I've seen some take as long as 11 or 12 weeks to fully mature, without counting veg time. I wouldn't say you have a light leak because then your other plant wouldn't be flowering as it is.
