Fan leaves browning

I can't put my finger on what's causing this issue

It's only affecting one plant out of 7 that are getting the same nutrients (botanicare line including cal mag). Also it's only on 3 or 4 large fan leaves

Auto 1 week into flower, it's been progressing over a 4 day period

Coco/perlite hempy mix

No issues on other plants

It looks like a magnesium or calcium deficiency also what color is the stem

The stem has a slight purple towards the leaf

it does look like a magnesium calcium ratio issue

but don't be quick to add more until we figure out if its lock out or def

can you give me a picture of the % analysis info for each bottle of nutes your using along with how many mls per gallon your mixing for each

Hopefully it is an easy fix^^

Looking for an opinion on what people think went wrong here

I run botanicare

Bloom
Karma
Cal mag
Pure Blend Tea

I use the ratio recommended by their online calculator per 1 gallon
