Help, my 8 week old is having problems

I have a 8 week old clone. It's S.V.F. I have been growing it in miracle grow. I know it's not the preferred soil but the plant has been perfect until I move it from a 2 quart to a 2 gallon container. The tips are burnt, the taller leaves are yellow and spotted. See pics. This is my first plant.

give it some good fertilizer. That is a deficiency, not burnt.

it needs some cal/mag for sure.. no questions ask..gl
