I have no idea on what this is. I've noticed the deformity ever since they were a new born set coming up. This is the first time I have ever seen holes on a new set of leaves. The next set of leaves looks as though it has a little deformity coming, but nowhere near as serious as this set looks like. I believe that I have been doing everything correct or close to, based off the rest of the set of leaves. I have not noticed the problem on any other leaves, nor on the other plant. I've looked very close on the underside of the affected leaves, and haven't noticed any pests. I know that some pests are very hard to see with naked eye, but I have some very good eyes. Take a look at these pics and let me know what you think.
