Mr nice is a great strain and a great smoke. If its the same mr nice its genetic makeup is g13 x hashplant. you're definitely in for a treat!

as far as your baby, it looks overwatered to me. what kind of dirt do you have it in? you shouldn't be feeding with every watering. maybe once or twice a week. Make sure the soil dries out all the way in between waterings

I'd personally build your own closet. Some white poly plastic, a zipper and a few tools and you can replicate a tent fairly easily!
