Welcome to the forum.
It’s not necessarily a deficiency. How about pics of the whole plant? What soil are you using? Are you pH adjusting your feedings? Do you know your runoff pH and PPM?
Thats a heavy fertilizer to be using for autos my man. Looks like there could be some calmag deficiency too.
Absolutely no clue:woozy_face:
… I live in a country where marijuana is illegal and there is absolutely nothing you can buy in terms of soil except what you prepare. a little black soil, cow poop, some dried fruit peels, a little coffee, worm castings…and happy frog to complete, the rest like ph, temperature and humidity I’m learning in places like these. The shortest answer would be “I have no idea”
Any suggestions?? She looks ok except for that
Resembles PH out of range, this will create deficiencies. 
Yes, that’s one problem… go up an Dow between 5-6-7… water,water.water. Can’t estabilice. 
Sounds like the soil you’re using is not buffering the PH. I would recommend a PH of 6.5 and follow a drench to drought routine. Depending on the vessel size the drought period could be 3-7 days before it’s time to feed again. I’m assuming you don’t have a TDS pen to check the run off PPMs
You assume correctly, I have absolutely nothing. the basics according to what I have been learning from people like you. I myself am amazed at how far these plants went with my lack of knowledge. a PH and soil meter from Amazon for 15 dollars 
and between us I don’t think it’s very reliable! From the beginning (newbie excitement) a series of errors with different types of soil, lights, food… You know!. I’m going to leave it without many changes and give it a break from watering and see how it reacts. Thanks for the help. love and peace man! 
Before you get too far in I would add oyster flour as a top-dressing which will provide C and act as a PH buffer.
Not trying to comment on something I know lesser about till now and joining this has been absolutely fantastic and I have gotten lots of great advice and feedback but I wanted to let those who might not know or didn’t know existed but I downloaded an app called “picture this.”
It’s a great plant app where you can take pictures of any plant and I mean ANY PLANT and it will diagnose, identify and gives great scientific advice too! It’s a really good tool for these plants for when they get sick or anything! Can’t hurt to give it a try! I know I was glad after getting it! Here’s my newest addition to my girls, got one boy finally so I can have seeds for next year’s hopefully! Thanks for all the help everyone!!! Welcome my new 3 babies!
I am using liquid fertilizer “reefertilizer grow 20-5-10 in small quantities every 3 days. PH around 6/7. Also new in this thing, never planted anything
