You don't need to spray it with Excel. You're just wasting money doing that. It is also too wet inside. You want the top of the substrate a little more dry. It's about humidity, not moisture. When I converted my HC to emergent growth it all looked like it was dead before it came back in new growth. If you do see new leaves, rest assured the transition will be fine.
