Changed 15 g Pacific Gem to 20g of Magnum at 60 min boil 1.00pm Boil started Dry hopped with only 7g Motueka Hops and 35g of Pacific Jade on Day 5-7.
Based on boiling 20.25 gallonsliters at 1.059 for 60 minutes, this will decrease your wort by 1.00 gallonsliters, bringing your after boil OG to 1.062. You wanted an OG of 1.074. It looks like it will be under.
