Deficiency, fungus, pest??

Initially I thought I had a cal mag deficiency or Lief Septoria but I’m lost now and my plant is under attack. Can anyone identify what’s happening here.

I’m in FFOF soil and running the foxfarm nute line with calmag added

Check the symptoms against this and address the issue as a process of elimination...

Looks like p deficiency. Maybe from over fertilizing.

Familiar with that chart great but like i said according to that it would be a cal: mag deficiency. But that wasn’t the case, think my salts built up a little to much. Sledgehammered her hoping that helps.

Lots guys, appreciate yall
