So I'm a newbie to growing cannabis. This is my first plant and I don't know what's going on or how to fix this issue. Maybe a nitrogen toxicity problem or deficiency?

Ok, what type of medium is it potted in?

What are you watering with? Tap water, RO water? PPM pH? Any feed?
 
Watering with RO water, medium is foxfarm,fish bone meal,Rose and flower mix,azomite, and compost. I did a compost tea for her which looks like it started new growth.
 
Since young seedling I've been using liquid seaweed and urb in a spray bottle. Just till recently almost a week ago I did the compost tea. I just order some cal-mag so I might try a little of that to see if it'll help.Any suggestions on fixing her up!
 
My runoff water pH 7.2. The water I was giving her with the seaweed and urb was anywhere from pH to 6.9,6.5 and just recently 6.1.
 
Forgot to mention the strain is northern lights. Should I flush her? If so how? Worrying a flush might make the plant stress and make matters worse.
 
I've done the flush yet! I'm waiting till the medium dry a bit. When you say get a hold of the PH you mean from the roots or my watering? I'm going to start watering with 6.2 pH I just purchased Nectar for the gods Hades down. I was using general hydroponics pH up & down. The bottom leafs feels dry and paper like.the two really dark ones don't fine as dry! I'm keeping the temps at 74 degrees sometimes it fluctuate 74-78 lights on and 69-70 lights off. And humidity at 66-68 lights on and 60-63 lights off. I have the Spider farmer SF-2000. I also have 4 more young seedling also that's stretching. So my new growth looking ok she's become bush . I bought some Epsom salt I hear its good for plants in general not sure how to use this yet. So I'm I dealing with a toxicity or deficiency? ☹️
 
So now the new growth is starting a little dark green as well. And help in getting better?

I'm thinking it's a magnesium toxicity. I have no idea what I'm doing.... I pH her water at 6.4 today with half a teaspoon of Epsom salt in plain water! I'll give her some compost tea in two days or so. Please help!
