Looks like a classic nutrient burn to me. Flush and start again with a much lower mix.

Is this the only spot? Can you upload a pic of the entire plant? Also, fill this out and it will be much easier to diagnose

How many plants? What Kind?
How old are they?
Indoor or outdoor?
How big is your area if its indoors and is it well ventilated?
What medium/soil are you using?
Whats the size of the containers?
What's your lighting set up?
What's the temperature and humidity like at any given time?
What's your pH like, both medium and nutes?
What's the NPK of all your nutes?
How often are you feeding with nutes?
Any pests around?
What is your watering schedule ...
