Hello Again Everyone!

I bought this Miracle Fruit plant from the green thumb fest on 4/27. I repotted it in a slightly larger pot with unfertilized soil with peat moss on the bottom and top of the soil. I mixed in some Garden Magic nutrients in the soil. I fed it about 1/3 cup Garden Magic fertilizer. I water it on the weekends. I recently added some pine bark to the top of the soil per a friends instruction. The plant was healthy when I first got it. Now the leaves are droopy and look like they are going to fall off. The new growth is turning brown. the flowers that just bloomed turned brownish red. I REALLY dont want this plant to die. PLEASE HELP!

Thanks for any help!
