Hi here is my 3 day old seedling it goes straight at the bottom then sickle shaped is this normal its not stretching towards light its going away from light. I dont think light is to intense as my other seedling is straight I also have another seedling that dont look right i dont think it was planted down far enough as its curling like tap root is not fully in coco. i dont think sickle shaped seed is damping off as stems normal colour and its been like that 3 days. i also buffered coco with rhizotonic and a little canna a b and can i start using canazyme straight away because im re using coco

then sickle shaped is this normal its not stretching towards light its going away from light.

I have seen it with Cannabis seeds and with most every other type of seedling. At 3 days since germination it is not anything to worry about.

it'll straighten up once the trues are established and it points to the light.
