I had rotala butterfly and macrandra growing great, beautifully red for the first week or two then BAM super weird green tips and everything is growing either curled or downwards. I have rotala sp green, HC, HM, hairgrass, and Rotala indica growing great .. it's just the red plants.. It looks like calcium deficiency to me..
