Yeah Bacopa is the one that isn’t doing too well for me either at the moment, but they were originally for about 2-3 weeks when I got them. Could it possibly be because my tank just got done cycling and I haven’t done a water change in about a month?I have used seachem root tabs for my big Amazon sword and tiger lotus, but only twice in more than 18 months. I use potassium regularly. I never had good results with flourish, just seemed to get more algae. The best all in one fertilizer I have used is Azoo Plant Premium, but I believe it is not available in the US, there are probably other similar ones there. Bacopa never did well for me but swords and Cabomba do fine, even for quite long periods with no fertilizer.
