You still have some time left. The fall flow is probably going to start soon if it hasn't already and you can start feeding at the end of August if they still don't have stores or a good flow by then.
Assuming the | is the followerboard, I think you probably need to give them more room. Is your hive only 16-17 bars long?(e=empty bar, E=empty comb, F=feeder, h=honey, B=brood, =follower board, [] hive ends, o=entrance holes)

"You might run out of season before the natural transition to stores collection occurs."What they will "store," of course, is your sugar-water. You "think" that they're burning-up their available nectar building comb, but there's really no basis for that.)
So you feed from august until they stop taking it? You dont have a problem with them backfilling the broodnest early? I am light and am going to have to feed, I was hoping they would change my mind with the goldenrod and clover but they arent putting on anything. GAlthough everyone is giving good advice, please remember that advice is valid only within the flight range of THEIR hives.
For example, if the nectar flow goes from April until September (as in the southern US), there is probably no reason to feed, but if you live here in Falls Church, you feed from late March (when we get our packages) until the flow starts, then harvest in late July, start feeding again unless you want them to start consuming what you've left, and stop when the weather gets cool; then they are on their own. and that advice is only valid within the flight range of my hive. - Mike
