Cover that other hole in the res! The roots are probably JUST getting to the point now where they are poking out of the medium and you don't want them exposed to light.
They look hungry too. While you are fixing the other stuff, hit them with a foliar feed of a complete grow fert with 1/2 teaspoon per gallon epsom salts added to it if you have any kicking around.
The hole is totally covered, that was open just as I was testing the nutes. The roots themselves are white, BUT, they have like a brown on them but I was pretty sure that was from the nutes I was previously using which was brown and sludgy. The water is pretty fresh and looks clean (I don't see green algae or anything).

How much do you foliar feed it?

Thanks.
