Diagnose nutrient issue, looking for guidance. My sick lil girl.

[Frankster]

Here's the sick patient, and the leaves down below. Let me try and give a little of the back story. Ran out of Calcium Nitrate, so I've been using some organic mixtures, Kelp, plus amino acids until it arrived yesterday. I was mostly using the kelp, till I noticed the calcium defict, so added some of the amino acids instead, out of deperation. Applied it then, but I think I should have withheld the fishy part, anyhow, it's progressing fast, so I need to put this in check straight away.

She got a dose of Cal nitrate yesterday, and giving her a good flush, and regular nutes, and a bit of humics to burn anything that's left, and of course, reapply microbes. All the other plants look good except this one, so I just flushed the others with a bit of water, and added some humics, I want to throw these guys in overdrive. Tomorrow, I'll start them back up on a normal flowering regime.

Any words of wisdom, or constructive criticism welcome, and taken under advisement.
Ah, and the strain is Early Miss Auto x Frankenstein.
