Hello. I'm having major issues in late flower stage with cal mag deficiency, or what appears to be (to me).
I have northern lights plant that went almost completely brown and i consider it as dead:

And now it started sort of happening on white widow and royal runtz:

I have another plant in another tent but in DWC and its not happening there. For some reason just in rdwc where i have 4 plants.
Any thoughts on this? Im quite sure that i'm giving them enough cal mag supplement.
For 40 liters of water i add 20 ml of calmag, and I have around 50-60 liters in total...
Ph is 5.8
Ec is 720
Yesterday i took a pint of water, and squirted in about 50ml of calmag, mixed it up and added to the rdwc reservoir. Problem seem to be worse now.
