I don't think you should feed. I'm not too sure about the watering situation, with that Coco in there it should have a pretty good ability to hold onto oxygen. I've never actually grown in a pot with a peat mix, but I would think it would be something that could hold some air also. I guess what I'm running around in my own brain is possibly it's under watering? The reason I say that is a lot of guys when they use soil they keep it kind of damp dry, and that really doesn't work with Coco and it probably doesn't work with peat.
So if it were me I might water it heavy you know letting it get run off and then wait several days and see what happens.
But it really is a toss-up at this point you're just going to have to go by your gut I think.
