It is burning from excess nitrogen from feeding too much or too often, or both maybe. It is not potassium deficiency, which has quite different symptoms.

You've definitely got a potassium deficiency - do up a strong banana tea and start using it when you water/feed. The lack of a diary here doesn't allow us to give you any more information as to how or why this might have occured.. start a diary and then when problems/questions arise, the community will have as much information as possible about your grow and will be better able to help! Good luck!

Hi Gov420, That's nutrient deficiency, probably potassium. If it's the case measure you're feeding pH and adjust to around 6.5. Add some flowering nutrient to your feeding. Something with NPK like - 2-5-6 or 0-5-6. Can you post more info on your grow? What are you feeding the plant? What week is it on? how long it started flowering? If you want you can send a message through the chat.
