OK so I know it’s a deficiency but I don’t know which!!!
To help the growpros get you settled in try and fill out the below to the best of your knowledge! And if you can post some pics of the full plant 
. Although it looks a bit like what I dealt with Ph issues can look like several deficiencies and I wouldn’t want to steer you wrong my friend.
COPY/PASTE the below list into your forum post.
Answer these simple questions the best you can. If you do not know, or do not use something; Just say so; Or post NA (non applicable)
-What strain, Seed bank, or bag seed (photo or auto) -Age of plant -Method: Soil w/salt, Organic soil, Hydroponics, Aquaponics, KNF -Vessels: Type and capacity of container (fabric, plastic, etc) -PH and TDS of Water, Solution, runoff (if Applicable) -PPM/TDS or EC of nutrient solution if applicable -Method used to measure PH and TDS -Indoor or Outdoor if indoor, size of grow space -Light system List brand and wattage/spectrum -Actual wattage draw of lights -Current Light Schedule -Temps; Day, Night -Humidity; Day, Night -Ventilation system; Yes, No, Size -AC, Humidifier, De-humidifier, -Co2; Yes, No
If growing Hydro some additional questions:
-DWC? RDWC? Autopots? Ebb and Flow? Other? -Distance of liquid below net pot (DWC) -Temperature of reservoir -TDS of nutrient solution -Amount of air to solution
Always try to upload a clear picture in white light of any issues you may have to allow the community to assist you.

The strain is NYC Diesel Ani I bought femenized seeds from ILGM I’m using the Bergmans stage three fertilizer I’m using regular tap water as well as a tsp of cal mag with it I’m growing in soil an the pH is about 6.5 the last time I checked it the plant is about 7 1/2 weeks into flowering I do not know the run off pH an right now the light schedule is on 12/12
I know I gave it light burn the other day but some spots are a deficiency I just don’t know which either potassium or nitrogen ugh lol
I am not familiar with the nute line at all. What kind of lights are you using?
Environment is good? Humidity and temps? The tips curling upwards leads me more towards heat stress, and the coloring towards cal mag.
But please wait for the others to chime in. I am fairly new at this, and feel like heat stress and PH can also look this way.
When feeding you Ph the water as well?

Getting your runoff pH and PPM under control should produce improvement.

No I haven’t been testing the water but the plant has been fine up until the last week it’s definitely light burn because I have other smaller plants in here so I had it kind of close on my bigger plant a few days ago but also I know it’s a deficiency because the bottom leaves are showing it also so I know it’s a combination of both I just don’t know which deficiency lol
PH can look like a bunch of things, I would suggest Ph for every water/feed in.
Like @MidwestGuy put Ppm and Ph stability would help that lady get what she needs

Numbers first 
do your plants the favor and get them up on boosters to level the canopy as much as possible.
