I'm growing outdoors and I water every three to four days. You're growing under lights so it may need to be more frequent, I'm not sure, but I know every day is too much. Weed plants prefer dry soil rather than wet soil. My plants were weak looking when I kept the soil damp, but now that I water them less they look much better. You can check how dry the soil is by sticking your finger into it an inch or two, don't judge from the surface. Also, the roots could possibly rot from alot of moisture.
Hope that helped a bit!
