strange dust like coloring on seedling leaf

Hi everyone ,i am a first time grower and this is my first post on the forum.
I have a small indica wich has germinated about a week ago,everything was going fine but yesterday i noticed a very small dark yellow dust like coloring on the leafs(it looks like yellow "plant hair").
I am still using a peat pellet cause the seedling still has some space 2 grow in,i am also using a 5000K LED light for it.I am going to leave some pictures bellow(sorry for my camera...it just sucks ) cause i have no idea what it might be.
I also noticed the spots were getting bigger so i will update in a few days.
Help would be very appreciated

You are drowning those. Probably toast.

i always gave small amounts of water trough out the day and the leaves were always straight and healty,i overwated once when i tried moving it to a bigger pot and then skipped a day of watering and the leaves are now normal again(not drooping)
also there is no way i toaste it cause i check the heat and its kinda hard to do with a led anyway

it may look its burned but it doesnt rlly irl.im gonna try to finda a better camera to post some more pics tomorrow

oh shit i just understood what it was,its a ph fluctuation,i moved the soil once the realized it was fertelized so i moved it back.
Can i just leave my plant in the peat pellet and the spots will go away?

The seedling isn't sick. Some seedlings start out that way then grow out of it.
