hi,

one of the leaves of my lucky bamboo is turning yellow but it seems gradual. i noticed it last week, and it's still the same until now.

i water them every other 2 days to let the soil dry out between waterings. and i put them 1ft away from the window (NE) so morning light only hit it for like 1-2hrs.

here it is:

is there something wrong to how i'm taking care of it?

there are three of them in one pot and i just transplanted them 3months ago. The other two seems ok except for this one.

thanks!
