Hello, I am in my 3rd week of Veg and was my nutes at 800 ppm and noticed a few spots on the leaves on the smaller plants. I figured it was Nute Burn because there were little burn holes on a few of the lower older leaves so I lowered the nutes to around 500 PPM yesterday. I woke up today and Now I am getting dried up leaves with brown spotting and yellow spots. I attached pictures of the plant now. Also some of the leaves are bending up and dont look normal.

Please Help!
