why is my plant covered in these spots??

so a few days ago i discovered these the day after i watered with some nutes i saw these and then flushed my plants what is this???

somebody please help me with this..

its nute burn. either your plant is under a month old or you gave it too much. you flushed already so only give it water for a few weeks. then after it clears up a lil give it a quarter dose to introduce it to the nutes then over time you can give it half strength

Nute burn? too much feed i think

are the leaves towards the bottom of the plant? if so those are the leaves that are plants is not getting any use out of because they are getting less light and fresh air....maybe i light nearer the bottom of the tent would have stopped this but it shouldnt make much of a difference if they are lower leaves if the upper plant is still looking healthy

alright thanks man +rep
