help, plants are getting to tall

any guess on how much taller theyll get???

have they gone through the stretch phase of flowering yet? it looks like it but i dont know alot on sativas personally. if it has it probally wont get much taller, if not it could get another 5+ feet taller.

yeah the one i tied down doubled in size in a couple of weeks. so did the others

i think the one on the far left reverted back to veg due to a porch light cause it had preflowers like the rest but never grew more it started growing leaves again. . am i screwed cause its way to late in the game for all that shit.
