forgot to treat sparge water. pH of sparge was around 6.6 and should have been under 6. One of the kegs didn't get any oxygen as I ran out
Based on boiling 14.90 gallonsliters at 1.044 for 90 minutes, this will decrease your wort by 1.50 gallonsliters, bringing your after boil OG to 1.048. You wanted an OG of 1.045. It looks like it will be over.
