High FreshBanger,
You give her too much water and the yellowing is due lack of oxygen at the roots system.
Let the soil dry out now and after that give 100 ml water 10 cm away from the seedling.
When you do this the seedling needs to search for the water and cannabis plants love doing that. Then she will also develop a better and bigger root system and the growth above the ground is equal to the growth under the ground. So your plant will get a lot bigger too!
She could have been bigger but when you treat her right from now she will still become a great plant!
Happy Growing! 😋
