Sour Diesel Auto

I had a calcium and magnesium deficiency, now it looks like she has an iron deficiency, I'm trying to help her in all ways, we'll see what happens later! 12/7: I did a calcium and magnesium treatment with potassium molasses and enzymes, I wait for the mycorrhizae and fulvic acid to add something to the plant instead of always fertilizing, meanwhile the plant continues to make these burnt leaves that seem to be potassium deficiency!
