Leaf tips pointing down?

So I came across this issue once again this morning to a handful of leaves with a weird downward bending point at the leaf tips. I went and googled it for a while and found that its a debate between excessive nitrogen, over watering, or rootbound. Im going to rule out the nitrogen since I haven't fed anything yet, but I did just drench the pot yesterday and it could of not been fully dry.
Also, I am using a smaller coffee can, but I really dont believe its rootbound just yet. So out of my experience I would say its from over watering, since the only real change I made was drenching the pot yesterday til water came out of the bottom. Anyone care to put in their opinion?

What's that medium consist of?

Its fox farms, peat moss perlite and worm castings.

I think u should up size ur pot. For what u got going on, those roots need more room to grow and spread

So yall think its rootbound, could be.
