Hey Kurak your plant is showing signs of a fast progressing nitrogen deficiency. I noticed that you don't have a ph listed so this could be causing a pH issue but I don't see other signs of pH issues so she is just hungry. I also don't see any nutrients listed that you are feeding. A girl that size is going to have a big appetite so she will probably need some nutrients every 3 waterings or so. Hope this gets you headed in the right direction.
