Possible nutrient deficiency on Anubias plants

In my 20 gallon tank I’ve notice for the past couple weeks any new growth on almost all of my Anubias plants are growing in with holes on them. I have a few Anubias nana and a coffefolia. The coffefolia has always put out a new leaf every 2-3 weeks and was growing super healthy. It was the first one I noticed with the new leaves having holes. They look as to start to grow normal then when they open up they have holes in them. I will get some pictures up tomorrow of the plants.

 

Did you plant them in the substrate, for anubias, you can't bury the rhizome

The plants have been in the tank for almost a year attached to wood and rocks. They have been growing great till now.

 

Holes in leaves are usually a sign of a potassium deficiency. You should see an improvement after a couple of weeks.

 

It may be a deficiency (possibly potassium as coma1224 said), but, even if you fix the problem, the holes will not heal.

Another possibility is hungry algae eaters. I've seen Amano Shrimp eat holes in anubias leaves when they are hungry enough.

I will wait it out and see. I wanted to try out easy green as well as my seachem flourish is almost done. I got some pictures of them when I by or home from work today. All the green leaves with holes grew in last week. The one yellowish one is a new coffeefolia leaf it’s new leaves always start yellow and turn dark green once it has developed.
