Continuing calmag deficiency
What I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciated

Golden/Brown dots on leaves .. HELP :(
Can someone please help me identify what this is and how to fix it? I assumed it’s nute burn but that would probably hit the tips no? Any help would be greatly appreciated.

Black spots spreading // Need your help!
Anyone got a clue what this dark spots could be? It started in a corner of the tent with 1 plant a few weeks ago and now it has spread to another. I suspect pH issues and a nutrient lockout bc of that. Not sure if its the same issue though..Could be an infection as well...

Calcium / PH issues? Did I take the correct steps?
Am I on the right track to remedy my plant's issues? Seems like calcium deficiency to me. Soil test comes in at just under 6.5, my reservoir water going in is 7.3ph, in case its actually a lack of calcium and not the PH i've top dressed gypsum (and epsom salts).
