Girls started showing sativa signs in stretch phase. They entered week 3 of 12/12 and flower stage fully began, still they continue to stretch and is it normal to show not symmetrical stem stretching? Plants have 30% sativa in genetics
It looks like the standard indica stretch, your plants were 22 cm tall before thee stretch and now are 40 cm. If it were a sativa it would have tripled its size. It also has to do with the size of the pot you are using, a smaller pot will keep the final size in check. Ans it is very normal for some stems to grow more than others
Just make sure you have cut the N waaaaay down, and the plants should start focusing more on the buds. They might still gain a few inches, using up the N that the plant has already stored, but it should stop your nodes from spacing out like crazy.
