You didn't have money for Foxfarm but bought MG and 3 bottles of fert? The MG might enough, if not too much. I was thinking that the green looked a little too dark green, meaning probably a little too much nitrogen. Those ferts have calcium and magnesium in them. hmmm, if the leaf tips are turning brown, you might have an overfert condition. The golden spotting does look like magnesium def but I'm wondering that since you've given cal and mag, that it's more overfert than anything else. I'd say just water for a while, let the soil dry out between waterings, and see what happens. come back here if things don't improve.
