Grass foliage issue

Hello,I’ve been noticing some issues with my grass foliages during my day-night cycle

this is what it looks like during the day which works for my stylized game

as soon as there is less light(due to moving the “sun” component it starts looking like this which isnt really ideal

at night it also gets slightly blurry which can get distracting for the player

at dawn before the sun fully sets it looks like this

How can i fix this?I am using Unreal Engine 5.2
Any help is appreciated!
