Is my fizzy-wizzy DYNNNGGGG !!!!!!!!????????????????????

I’ve had her (lucky-bamboo) for about 3–4 months. Since mid-winter, her leaves have started turning a whitish, pale cream color. At first, I thought she might not be getting enough sunlight, so I moved her outside. But it was winter, so the sunlight wasn’t very intense and she doesn’t need a lot of direct sun, I thought she’d get better but she did notttttt.

I’m pretty new to plant care, so I’m not sure if I’m doing enough or maybe too much. I clean her pot every week (I really hope I’m not over-cleaning or under-cleaning it 😭). She likes water (I'm sorry, I like water, I wanted to grow her in water, I probably forced it upon her), so I change her water every three days. I also keep her outside when the light intensity is low so she can be happy but she is NOT happy. Ahhhhh!
+ Should I switch to soil?
and is her pot too small for her?

I love her so much please, how do I take care of her???
