you water them when theyre super droopy? theyre droopy as hell right now!
first watering plants, soil has to be COMPLEATLY dry at the top.
anyway, this doesnt look like proper cannabis plant. in my country theres LEGAL 3 leaved cannabis plants with no THC at all. but also there is plants with 5 and more leaves with no THC.
what im trying to say, plants in your hands could be usual weed, no cannabis plant, I never seen cannabis plants with flowers like that.
but dont give up hope, maybe im wrong, just water them proper and you be aight.
