get some pics up if u can...i had a similar problem and below is a pic of how my plant looked at the time...apparently it was a magnesium deficiency so i tried the epsom salt solution to correct the problem and it seemed to improve the health of my plant... i really cant offer any further advice without a pic..but if ur plant is looking like the one below try the epsom salt solution (i put about 1/4 teaspoon to 500mls of water and sprayed it on the foliage)
