mash temp came in low at 145. Added boiling water after 10 minutes to bring temp to 154. After 45 minutes added boiling water to bring temp to 161.
Based on boiling 6.70 gallonsliters at 1.055 for 30 minutes, this will decrease your wort by 0.50 gallonsliters, bringing your after boil OG to 1.059. You were planning on an OG of 1.059 so you are right on track. Nice job!
