Leaf tips yellow and curling down

about 2 months old help pls

mine are curling down but not turning yellow yet, i could use advice on this also

Im still new myself so best bet is to get anothers oppinion first. But, by the looks of it, it's over fertilizing. flush the plant with 3 gallons of water per one gallon of soil. Correct me if im wrong anyone.

As i said, wait to get another oppinion first cause im still studying myself, lol. But to me thats what it looks like.
