Leaf spots

Leaf spots, Cal def or fungus?My air flow is good and my humidity stays around 50 except just after watering so I'm leaning towards a calcium problem but I'd like opinions.

Leaf Septoria. Unfortunately dwarfed the hell out of her. I've taken off and destroyed leaves with any signs of fungus and sprayed the plant and inside the tent with Neem oil. 1tsp to 1l warm water and some washing up liquid. She won't die but I'll be lucky if I get a qtr oz from her.

My light reads at exactly 37k lux on the top of the plant. If anything it's a little low. The purple, which is very minor, likely comes from temperature fluctuations that I've been having to deal with. It hit a day high of 32.5 and a night low of 16. I got some leaf coat to try if it gets worse.

Petiole leaves are purple, light is too intense leading to lack of Mag, triggering multiple random deficiencies.

My pH is corrected to between 6.1 and 6.7. I use .25 Calmag to the liter every watering but I'm going to up it to .5 for the next couple.
