Hello - First time brewer here. I'm on day seven of fermentation. I've got a nice foam head on the wort/beer. It's not growing in size but doesn't seem to be decreasing much either. Also I see a lot of very small particulates circulating (moving up the side of fermenter) very slowly inside the fermenter. Wondering if this is normal. I'm brewing a Hazy IPA and tomorrow I will be putting the second set of hops in the fermenter. Fermenter temp has been holding at 64-65 degrees Farenheit.
