What is growing out of my dry rock during cycle period?

Hello Reefers
New to this whole thing and don’t want to get myself into any big problems down the road. What is growing out of my dry rock that has been cycling in my tank for 2 weeks now?
Thanks in advance

Looks like dried stuff that was stuck on the rock.

Okay so nothing to be too concerned about? I’m hoping to add fish in the next week or 2 depending on my test levels. Everything is looking good so far!
