Hello everyone, how yall doing? Well, i bought this amazing sunflower to mother's day. It was from a common market, not a gardening specialized one, so probably it's not well threated. Now it's kinda cold, 20°C max, so i think it's not ideal. The second photo is of the windows she bathes, this is the sunniest part of the house and kinda have low to medium light all day. Third pic is showing the leaves i removed, some are just yellow but 2 are specially crunchy. 4th pic is of their roots (i don't know if this is important)

Any tips? I didn't used anything other than water once a day
