There is a definite correlation between K dosage and the holes in the leaves. As I increased the K dosage, the holes appeared. Simple as that. The K2SO4 dose increase, the introduction of N through KNO3 and the Flourish, have all increased my K levels.
I think I am going to do the next three water changes, and not dose K. I will dose the Flourish and the KNO3. On the fourth water change, I will go back to the 1/4 teaspoon of K2SO4, as I had been doing. I will talk to Jay, and possibly dose a little Ca and see what happens.
This is not devastating, just annoying. Alternanthera reineckii is not a rare or expensive plant. If I have to replace it, I can do it without a problem. I would just like to find out what is causing the problem so I can help other people with the K / Ca answer.
