1.69 lbs after 24 hrs under fermentation, (July 15). 3 lbs after 4 days under fermentation, (July 18) little to no activity on bubbler.
Based on boiling 6.50 gallonsliters at 1.052 for 30 minutes, this will decrease your wort by 0.50 gallonsliters, bringing your after boil OG to 1.056. You were planning on an OG of 1.056 so you are right on track. Nice job!
