I feel like I am not so much the beginner anymore, but I feel that this might be a beginner question. I bought a finish Hydrometer a while back but haven't had a big enough tube to use it in until now. I think that the reading I am getting here is 1021, minus approximately 0011 or so for a reading of approximately 1010 or even 1009. I used US-05 and it should finish at 1009. OG was 1052 (was supposed to be 1055). It has been 12 days, and the Krauzen fell around day 7. Am I reading this hydrometer correctly?
