nope.
Its a spot on a leaf caused by the lack of phosphorus at that point in time that has since died and turned brown forming spots that look like that. Probably caused by your lack of using basically no nutes.

oh ok mg is miracle grow I get it now I thought mg was mag. Yup lots of nitrogen. Ride it out or the only way I can think of to deal with that is to flush the pot every watering and renute with a bloom nute and add microbes and dont do this without microbes.

You think the brown spots is nitrogen toxicity? I'm gonna start feeding this soon if she's bonces back right now I'm just using straight water

Pretty sure that's just one part of a two-part formula. Do you have the base?
What makes you think you have too much nitrogen? That root farm stuff ain't going to cause that. It has pretty mild NPK ratio. I'm leaning towards a phosphorus deficiency.

I am getting the claw on the top leaves that's why I'm thinking nitrogen and I don't have the first part as I just want something with less nitrogen

right on /// aint autos lite feeders idk =====what ppm you feed at?
not much else to go on by the pic might want to use less nitrogen.

Sometimes too much light will cause that. They do it as a defense mechanism to try to reduce the amount of surface area that's getting direct light. Or if they get too hot or too cold that can cause it. So can over watering. And so can problem with phosphorus. And given the spots on your leaves, I'd wonder if that wasn't more likely. And to make matters worse: some plants just do that.
Is that soil you're using an inert medium? If not, how much nitrogen did it have in it?

The bag said it feeds for 2 months whatever that means

You need to know what your soil is composed of and in what concentrations. It should be on the bag. Or else it's a crap shoot from the get go. Otherwise, you can't be sure how much you're changing the soil.
