Not quite sure what is going on with my plant.

just wanted to know if I could possibly get some help on my plant. not sure if she is dying or if i'm stressing her out. I recently transplanted her about 2 weeks ago to the larger container didn't have anymore soil that I was originally using so I went and bought some newer soil. that is what I am thinking is making her yellow & the pistils brownish red. tbh I never intended to grow I just threw some seeds out one day and she popped up. so I'm not even sure what strain she is.all input and tips would be greatly appreciated.  

 

lets see I was using a topsoil perlite and pete moss medium no nutes because I honestly didn't even notice it growing and had no funds to buy nutes so I just been watering it. I did switch to a vigoro potting mix when I got the bigger container. I thought maybe I was over watering it but I read somewhere that you really cant over water after the vegetative state. it's been growing since the end of June I would say.  my setup is outdoor for sure nothing special as I was not really prepared to raise this plant but i'm following outdoor grow procedures that I read online. I plan on growing again but doing it right. just wanted to know if I was killing this one or if is maybe ending its flowering stage. then again I have no Idea what strain this is. I see no bananas or sacks and the pistils are still pretty long. thanks for your input. 
 
also the potting mix that I recently switched it to may have a fertilizer in it as it says "feeds up to six months" I tried flushing the soil first to hopefully avoid that. I haven't watered in about 4 days now and the soil is still pretty moist up top.
