Help - Im thinking P deficiency but idk

Hi all, im wondering if you all could tell me whats going on here. This problem started last week after i added some Mg to the water before i topped off this DWC pot. Started getting purple splotches which grew worse into these brown spots. This started on the old fan leaves and has worked its way all the way to the sugar leaves. Last week 3 days after symptoms started I drained and refilled with 1/2ml/ gal. of calimagic - 5ml/ gal. of GH micro - 5ml/ gal. of bloom - 1/2 tsp MG - 1ml/ gal 12% H202 and 1tsp of mad farmer MOAB. Symptoms seem to be progressing rapidly. I wasnt too worried, but i dont think she will make it to harvest at this rate. She is in week 4 of flower btw gorilla cookies auto - fastbuds - my rez ppm is sitting at 940 starting off with tap water of 190 PPM Thoughts?

maybe the pics would help, huh? lol

any ideas? this has progressed significantly. Same symptoms, just on leaves with direct light contact all over the plant

Honestly you're probably right. Ph looks a lil off too, or you have an imbalance. You can see what's going on, the sooner you realize skills matter and fancy nute bottles or soil doesn't. You'll be off and running. I think you're seeing what's going on pretty well.
