OK, So I have searched the archives and it says that holes in the leaves of amazon swords is caused by a potassium deficiency. I disagree. I have been pouring the potassium in my tank at the rate of 1/8 tsp KNO3/Day (in a 50g water column) and the older leaves are still getting holes in them. Should I increase this? Any suggestions? Btw, I also only received part of the last archive.
