Hey Night501, good to meetcha. Welcome to our group. It sounds like you're doing ok, but I have no idea what those lights are either. Do they have a wattage printed on the bulb?
You want to use NO nutrients with the Miracle Grow potting soil. The Brothers Grunt are our Miracle Grow specialists and can tell you all about using it.
Everyone who has used additional nutes with the MG soil has reported nitrogen burn. The Bat crap is amazingly high in nitrogen. You don't want that stuff in the same room with your plants while using the MG soil. Plus, Bat crap is LOADED with other nasty stuff that could hurt you. When you buy it from a commercial dealer, it's been sterilized and any harmful impurities have been neutralized. Please leave the fresh stuff for the bats to play in.
If The Brothers Grunt haven't stepped in by tomorrow evening, drop them a quick line in a PM and ask them to take a look at your situation.
Good luck to you and once again, welcome to the family!
