Don't bother with coco any more man. I had this problem 3 times. Check my diaries you will see this little fuckers I throw in a bin after 3 weeks:) my advise get yourself canna terra soil mix , organic plant food, I am using bio bizz, and you will never have this problem again. Check my last zambeza diaries, canna terra and bio bizz. Grows perfect and no headache. Peace
