Curled brown tips

since yesterday the top of the plant seems to have perked up a little, looks firmer and the leaves seam to be strong but the tips pf the leaves all of them even the new ones are brown and point up or curl up, and the plant is still lime green, all of the new shoots that were groing on the bottom seem to be really sick and droopy and the ne shoots are drying up befor they become leaves, what's this about?

When in doubt flush them out!works everytime!
