No stored honey

Pennsylvania. 1 hive going since June. I’ve fed them 1:1 sugar water most of the summer and now fall. They wouldn’t take it around July to August so I slowed down then picked up again in September. I inspect about every two weeks, have done two mite treatments and one more later this month. During the last inspection there was zero capped honey. I suspect robbing but haven’t noticed any signs. Still feeding them 1:1 and this week they’ve started to drink all of it every day, four mason jars on a top feeder. I put out another feeder far from the hive with 1:1. I start feeding candy board once it gets cold enough. Is there any hope for this hive?

I’m a first year keeper. Did not harvest this year. There were two other hives that failed in the spring and I had my hopes up for this one.
