too much or too little?

Hey Afn i have an autoflower in a 5 gallon pot. i started it in roots organic original 3 gallon smart pot and spilled cal mag into the roots a month back so i then flushed it and moved it into the 5 gallon its in now but filled the rest of the 5 gallon with coco coir. I have been feeding it very light nutrients at 1/3 the recommended . I woke up to a plant that started having all the fan leaves turn yellow pretty much equal throughout. I fed it at max dose and came home to a bunch of fully yellow leaves (mostly fan leaves) all the way up to the leaves poking out of the bud. I cant tell if too much or too little nutes? i know i couldnt tell that fast because a lot of damage had been done and is currently playong out. i am leaning toward not enough nuted since its in coco but am not sure . Ant help would be immensly helpful!

I started out fully stnthetic and jave since switched to medi one by green planet, finisher, and org cal mag

Looks like nitrogen def so i would start feeding veg nutes to green up those leaves.

-- hey CC.... it's a bad mix to layer coco on top of true soil, they are very different mediums, and coco is particular can be bitchy,... be sure to use Ca-mg from here out, coco is a major Ca hog due to it's odd CEC properties....
Symptoms, did they start tops first and worst, or visa-versa? N defc., some of which is normal, goes bottom up almost always, as it's readily mobile within the plant... S defc. shows very similar overall color fade, but it goes top down because it's immobile, and in high demand now during bloom... What did you feed? Prior to this, how much, how often?... One dose will not show a fix that fast in any case,.... Oh, saw the nutes, get me disage/ freq. anyway, and the NPK#'s too please,....

Been here! Follow @Wairas advice. I had 3 gallon soil into 10g bag filled with coco, A circle of soil with coco under and around... Watch your water! Issues not letting the coco dry out letting the soil to dry enough. It worked out, but is better one, the other, or blended. The coco is inert, I would expect your feeding is going to increase as well, as those new roots are looking for food.
Eye on medium pH, that may also be an issue as the two may vary.
