You have SERIOUSLY over fertilized it, not only does it not need any fertilizer at that age, but you've given it sticks, AND liquid, and its grown in compost which has more nutrients than regular soil, complete overkill.

Don't bother with the sticks, and just use the liquid once every few weeks, and at a diluted strength to begin with.

Your best bet now is to "flush" that plant, get run lots of water through the soil to clear out all the excess nutrients and to put it back to point 1.

Good luck
