Ok I took the vals out yesterday, trimmed the decayed and dying leaves and a bit of the roots as well. The root looked good, BTW. So replanted them making sure they are not buried deep. I shall hold off on the Excel. I know my tap water is on the softer side, but I don't want to do anything to increase the hardness. I added couple of Osmocote gel caps near the roots. The plant should get better lighting now than before. I will dose Flourish Comp about twice a week. Hopefully, this will my vals. I have added some pics - first 2 showing the black lining on the leaves that I mentioned before, thirdone after trimming and the 4th after replanting..... Let me know your thoughts.
Thanks a bunch.
