You're very welcome.
I checked the Cottage Farms website to learn the nutrient ratio of the bud n bloom which is 18-24-18. Nitrogen, Phosphorous, Potassium. "The main nutrients that promote rose blooms are Phosphorous and Potassium. To increase your phosphorous, you can add a nice helping of well rotted compost, or a handful of bone meal worked in. To solve a potassium deficiency, again, a good helping of well rotted compost helps, or alfalfa meal (I buy mine at a farm feed store as it is cheaper), some fish emulsion, or some kelp."
I copied this from another post I found and have referred to a couple of times. It's written perfectly and I couldn't have said it better. I do want to add that I think you are feeding too much nitrogen
with both the coffee grounds and the bud n bloom. I would try the bone meal and see what happens.
Have fun and keep us posted.
