Most of my plants are going OK but I'm noticing this eating away or burning in some of them. My Cabomba has almost all died out.

Holes in the leaves are sometimes caused by a potassium deficiency.

What is your dosing regiment? Have you moved these plants recently?

I am having this same problem with new red ludwigia. I just planted them about 3 days ago and they have holes in the leaves plus they also look like they have been burned around the edges of some of the leaves with a flame (black burn like appearance)

any ideas?
