I live in Auburn, Washington. When I planted these hardy hibiscus, they are around 4-5 ft and have buds and flowers already in July 2015. Have not seen any new buds forming after they bloomed. Now it's mid July 2016, grew same height, looks healthy gets 6-8 sun daily , water everyday, fertilize 2X a month. So far only one (out of 7) shows some buds forming, am I getting buds on the other six? (they are all of same variety)

Two thoughts: not enough sun, not enough water, not enough heat (oops, that was 3). I would guess heat.

It think Daisy is probably correct. Looking at your temps, they look very low. My Hardy Hibiscus generally start blooming in June. By then the day temps are already around 90 and night temps are in the mid 70's. Our night temps in June are as high as your day temps in July. Give them some time. Also I'm wondering if you may be over fertilizing them. Hibiscus fertilizer is formulated for tropical Hibiscus, while Hardy Hibiscus are derived from five species of native US Hibiscus. I don't fertilize mine at all and they bloom like crazy.

Welcome! Daisy is right on the heat and water. They are swamp plants. They are one of the last if not the last plant to break winter dormancy.
They are like ornamental sweet potato and periwinkle, they only like to take off when the soil starts staying around 70. Your daytime temp is in the 70s and night in the high 50's. I think if it gets warmer they all should bloom. Keep up the watering. Mine loved the heat in Texas but could not keep the soil moist enough. Maybe if you have not already mulched around them , I would also do that. May joy be at your doorstep!
