Deficiency or burn?

What's up guys. I have a plant that is 58 days old and it is having some "issues." I thinks it might be lacking a nutrient(a nutrient deficiency) or something else, and that's why I'm here to find out what's going on. Any suggests or ideas help. Thanks. Here's a link to the grow. https://www.rollitup.org/general-marijuana-growing/788438-my-second-grow-kandy-kush-12.html
