their bitchin you out cuz they aint gettin enough light. jk. they need better light, they are stretching. what i would do is try to get at least a small flouro and put them under that. then i would either cut some straws and slit them, then place around the stem to support them if they start to lean over, or i would more than likely re-plant them deeper and new roots will eventualy grow from the buried stem. if you dont do anything, they will dwindle away. good luck.
