Okay the first problem i see here is the big fan leaves near the bottom of the plant are not getting as much light as they would like so they are dying off.
I see you getting the N Claw on the leaves but your also getting a pale colour too. That little spot on the leaf is either nute splash or a good sign that this girl is ready for Bloom nutes. Id say because your getting an N toxicity and yet the leaves are going pale means its time to make the switch from veg to bloom nutes especially when you get those little spots on the leaves.
If you have some trace elements, add it to your feed and it will sort out the pale colour on the leaf tips just make sure not to confuse this with nute burn.
Everything should be fine if you take these steps.
