It might be but the way your plant is growing right now I wouldn't back it off much.

Give it some more light, it wants to use that N up but needs light power.

Agreed. Flush with pHed water if it gets worse fast but most of us see a bit of nute burn like that at some point in every grow.

I realized its actually been quite some time since the last feeding and im noticing some yellowing along the blades of the leaves as well. I believe it is Potassium deficient. What are youre thoughts?
