Strange Toxicity?

[Verminator]

One thing to note. When you moved them did you trim the roots off allowing for fresh growth? No idea if thats relevant to you, its just when i moved my perfectly healthy and largest plantlet i trimmed the roots and re-attatched to the wood. You'll see what effect its had on my plant from the following picture, i hope.

I trimmed the roots but the leaves looked a bit different than that photo. Here is one old leaf that took longer to deteriorate and is still on one of the plants:

All of the other anubias leaves that melted away looked much the same. They were all the ones that had the initial brown spots on them and darkening leaf edges. Not sure if trimming the roots had an impact, but if it did that to yours then it probably contributed to the poor condition of many of the leaves. That + Excel spot treatment + a change in parameters due to beginning the EI regimen were probably all culprits. Wish it had been a more isolated incident so we could know exactly which change had what effects
