rick42_98,
Cossack is right, another flow on the way, but if your bees are in the area of heavy urbanization, you might not get one, goldenrod is not a plant you'll find in manicured lawns and weed-free gardens, if I can remember correctly, Wyckoff is crammed with homes, is it not :?
With the info you have given us, I believe your bees have gotten off on a bad start, feeding them all along will only weaken them more and the treatment may not help. :(
