Default Splitting a batch and strange smells

So I made a 2.5 gallon batch recently and after 2 weeks in the primary and doing my hydrometer tests I transferred my brew into two 1 gallon glass jugs and let them sit for 2 more weeks. I left one in the fermentation chamber at about 68 degF and put the other one in a cabinet with an ambient temp of 70degF(just to see what differences(if any) would come of it) I bottled last night, and transferred into my bottling bucket/bottled one jug at a time. The jug out of the cabinet smelled and tasted excellent, besides being warm and flat. But the jug from the fermentation chamber has a strong sweet smell/taste, which with my limited knowledge would guess is either fusels or green beer. I separated and labeled the bottles so that I could record the differences after 3 weeks of conditioning.

Now that I've rambled...Any idea as to why this dramatic smell/flavor difference could've happened?

2 degrees isn't going to make a difference after primary ferm was complete.

Only real possibility is if one of the jugs caused and infection or has some other residue in it that is giving off the "strong sweet smell/ taste".

Both of the beers are green so that is not a consideration. Fusel alcohol has a harsh boozy bite.
Did you taste both of them before adding the priming sugar? If you tasted both before adding the priming sugar then the difference could just be perception or infection. Was there any signs of a pellicle formation?

nothing visible, they were both very 'clear', no bubbles or anything visible. yea i tasted both, one didn't have any off flavors that i could tell, the other was very distinct. Both of the jugs were brand new, so my only guess is some sort of infection, I've read on here that some infections don't show any visible signs, I'm going to wait it out and see what happens, but looks like i will once again enhance my sanitizing ritual..live and learn haha, appreciate the info

PBW to clean post brew/before first use...and I use 1 step to sanitize, I've read numerous posts about it being good to go, and my lhbs didn't have star san in stock so i over sanitized with the 1 step to be sure..couldve made a mistake with that, and if i did please correct me.

I am not familiar with One Step. Could using to much in solution cause the problem taste? I don't know.

It's a no rinse, and there was no visible residue left..This next batch will be my first one with temp control start to finish so i guess we will see if maybe that is the culprit

Double check your yeasts optimum fermentation range. Look at the manufacturers web site for reviews of the yeast. Perhaps others had a similar problem at certain fermentation temperatures.
