Young plant slightly yellow curling

Hi, i have a young plant that was doing well but recently the leaves at the top have become slightly yellow and some leaves seem to be curling down a little, i have been watering every 2-3 days, have i been overwatering?
the soil mixture is half soil half miracle grow compost with a bit of blood meal and some small rocks to help drainage

Just To Guess, Were's The N' In The Soil Mix, At... It Maybe Time For A 1/2 Str. Nute-ing. I Also Would Agree With You, To Much Water, Step Back A Bit, And Give Us A Better. Pic Of Pot Size, That Will Help With The Watering Questions...db. Imo.
