Brewed NB Plinian Legacy extract kit. As instructed, at beginning of 90 minute boil, I added 4 lbs dry extract, and got a quick hot break, and proceeded. As instructed, with 15 minutes left to boil, I added 6 lbs liquid malt extract. At 0 minutes, pot was still foaming big time from the syrup addition. I gave it another 15 minutes, but still not hot break, so I flamed out anyway, and proceeded following the kit's instructions. Much solid material remained suspended in the wort. OG was 1.050 vs. expected 1.070. Should I have continued boiling until the hot break came?
