If you're already adding Mg it's likely enough, it's probably running into absorption issues. The first and third pic look like Mg but the second more of a lack if N. I bet you have salts building up in the rootzone. Pretty common issue around midflower that often gets misdiagnosed as a deficiency. Collect some runoff data and if that's the case give her a good flush.

Nitrogen toxicity mid-flowerSo I overfed during veg and now my plant has nitrogen toxicity. Besides making leaves super dark, crunchy, and yellow it has also made my buds pistils curl and brown way too early. I’ve been flushing often with water. Is she a lost cause or should I ride it out for 4 more weeks?3 years ago

Yellow Cotyledons?NLxBB was born with yellow cotyledons. The shell was stuck after sprouting so I had to help remove it. Took around 2 days before I saw them barely open with new growth. The new growth is green and seems healthy. Is there any reason why this is happening?Leaves. Color - Yellow

Yellow/Brown/Spotted/Crispy Lower LeavesWhat is wrong here? Gave an extra dose of nutes but the problem only seems to be getting worse and spreading up the plant. Definitely effecting the bottom leaves more. Others said to just increase N-P-K ration, but this seems like something specific.3 years ago

Deficiency or Nute Lock?I was a told a week prior I was feeling too much. So I stopped. I left town for 4 days and came home to the current photos. One looks like nitrogen deficiency, the other looks like calcium deficiency except I've fed 1tsp of tiger bloom, .5tsp of Cal-Mag and big bloom last week.3 years ago
