For two weeks now I have been EI dosing plantex csm+b, K2SO4, and KH2PO4 with the 50% water change at the end of the week. I wasn't dosing KNO3 because my nitrates were staying around 10 ppm less than a week ago. I tested today, found nitrates at 0 ppm, and dosed the KNO3.
So, one stem of rotala has new growth with stunted and wrinkled leaves, and none of the other plants show any problems. Is this a result of the lack of a nitrogen source or possibly a calcium deficiency (only other one that seemed to fit)? Last time I tested, GH was roughly 3 dGH.
