OG was only 1.034, very low implying only 56% efficiency, but mash was complete based on iodine test. Was the Rye malt not properly crushed?
Based on boiling 3.25 gallonsliters at 1.036 for 50 minutes, this will decrease your wort by 0.83 gallonsliters, bringing your after boil OG to 1.045. You were planning on an OG of 1.045 so you are right on track. Nice job!
