Sour Problem

ok so i just started two auto sour plants. They sprouted a few days ago an all was looking well. then i looked at them the other day an noticed that one of the sprouts starter leaves are turning a white color, never had this happen before an not sure why it's turning white. the other issue is i'm starting to see lil white mite's in the soil they don't seem to be on the plant just the soil i tryed looking them up online but can't seem to find any info on them any help/advice would be great thanks guys.

the white sounds like bleaching. make sure the lights arent too close. this could happen if the light suddenly got stronger than it used to be... you can use garlic or just spray your plants down with water to get ride of pests
