Hello there, did my first attempt at mead tonight and of course I screwed something up. I forgot to add the yeast nutrient, I realized it right after I put the airlock on so I quickly put a teaspoon of it in. Am I screwed or is everything gonna be ok. I'm so nervous about it

I appreciate any and all help!
It's a 1 gallon, technically melomel because I added some organic blackberry juice.
