Brown marks on leaves around 4 weeks into flower

Hey guys me again
I have ran into a problem about 1 month ago I ran out of cql-mag. Totally forgot to reorder some.
10 days ago my sour diesel auto started showing signs of calcium deficiency with little and minor brown burnt like marks on 4ish leaves, so I remembered about the calmag and re ordered.
Now the last photo is the main cola and I think I'm about 3 or 4 weeks into flower but all the leaves now are showing this and even the little leaves around the buds too?

Any ideas or helps ?

I used calmag as soon as I got it and I seen that you wait a week for it to make it better but its getting worse !
What can i do ?
I am running 600w hps and its currently 30inches away from the plant.

Am I safe to let it just grow ? Do I chop ?
Or am I doing something wrong ?
It is a soil grow and I am using biobizz bloom and max , watering every 2 days ish as I don't want to over water and also got told to put my first knuckle of my finger into soil if dry to water if damp then don't water so currently feeding every other day.
Room temp is always around 24 , 25 degrees and rh is around 50ish. Inlet fan for air and a rhino carbon filter for the exit air.

Really confused as first grow and my other ladies are not acting like this but I do know the sour diesel is part of the saliva family is this the case ? Or is it not calcium ?
Really don't want it to rot out or damage the plant as its growing really well and its a small in height plant but producing fat colas currently and dense.

Thankyou guys for all your input

How quickly did it get worse after you used calmag?

Had a look today and it has got worse today, some of leaves now bending over and look like burnt like no life left ? Are we safe to say that possibly root rot possibly has taken its toll ?

Oh i forgot to say would it be this ..
I had a ww after 8 weeks it wouldn't flower which I thought it qas an auto ? So I swapped my lighting from 18.6 too 12.12 after a week wouldn't flower so I threw it out. Then put the lighting back to 18.6 would it because of this ?
