Had issue with dry hopping. Put in whole leaves in the primary. Need better method like going to a secondary or using pellets.
Based on boiling 6.70 gallonsliters at 1.061 for 60 minutes, this will decrease your wort by 1.00 gallonsliters, bringing your after boil OG to 1.070. You wanted an OG of 1.072. It looks like it will be under.
