Calcium lockout???

[bearhair]

Hey guys and gals.. my poor beautiful girl is sick. Ive done some research and i think she has a calcium issue. Don't know for sure, could be deficient or excess.. I've read magnesium excess can cause a calcium lockout and I did give her full strength g.h. kool bloom along with g.h. micro and bloom..noobie mistake.. she is a good sized auto so I thought she would handle it well.. flushed her with .8 ec nutes in r.o. water.. this was part of my first coco grow. Damn she was doing so well.. she was on an auto feeder similar to the coco for cannabis set up. But bought a bigger tent and since she was the only occupant I've been hand fertigating as often as I can, at least twice a day usually 4 a day.. any suggestions would be appreciated..

Hello - overall she looks good, and nearing the end, so you just have to keep her going.
I think you did right by giving a flush with EC.8, this is the stage where she needs the most food so cutting it down for too long will reduce your results.
It looks like a Mag issue, but to be fair cal, mag and a couple of immobiles will tend to show similar burns on the leafs.
The burnt stuff will not improve, after your flush keep an eye out for new discolourations and take it from there
