I think I'm ok.....Java Stout

Pretty sure I'm just paranoid since a few brews ago I 'caught something'. I wanted expert opinion. See attached pictures....do I have another infection?

I brewed a kit from Midwest called Java Stout but modified slightly. I added 1lb of sugar, 8oz of maltodextrin with other fermentables and 10oz of unsweet cocoa powder at 1st hops.

This is my first Stout. I've checked gravity the last 2 days and it's stayed constant (been in primary 1 week). When checking gravity, I noticed this stuff is super 'thick'....it's pretty slow/thick coming off the hydrometer. I'm guessing that's the maltodextrin?

Heck I'm here...one more question....
I'm adding coffee and 4 vanilla beans to secondary.
1. Cut and brew beans with coffee or...
2. Soak cut vanilla beans in whiskey then add to secondary??

Looks normalish

You are fine put the lid on and leave it alone.
