HI, I see you are in PA with humidity. and again looking at your leaves…. they were overall way lighter green leaves than a healthy Queen of Sweden, sone yellow, and dark green veins & partial dark green leaf w/ light green spotches. Your rose bush had nutrient deficiences. i would recommend a balanced nutitional orogram is needed for your rose. Balanced organic living soil and balanced organic fertilizers I consider most beneficial for a thriving rose.
Many nutrients work together to create a balance that feeds the rose well. Too much of any nutrient or too little can cause rose to show problems…..too much acid, too much potash, too little nitrogen etc , then rose becomes imbalanced and all sorts of problems…. diseases… blackspot … yellow leaves… too light green leaves….mottled leaves can be distressed… little blooms or no blooms….insects prey on it more.….more diseases. Thus an unhealthy rose.
Nitrogen deficiency-light green to yellow leaves, poor stem growth, slim small leaves-green growth hampered. Too much N itrigen however causes burn! .
Phosphorous deficiency is seen in lessened or sm rose blooms and poor root growth.
Diseased, too much insect damage, or mottled leaves may be Potassium deficiency which aids in overall health.
Less trace elements such as iron, magnesium, sulfur, calcium, & other micronutrients and leaves curl, veins are dark green but leaf lighter green … a number of issues can be created by an imbalance.
Your leaves look like they have seceral issues, generally an imbalance of nutrients.
I suggest a balanced organic fertilizer to be used to cure a rose problem usually. I like Straw suggesting Espoma Rose Tone & ( Plant Tone is good alternative) . I love the organic smell of these Espoma fertilzers telling me they have real chicken manure, real alfalfa, real bone meal and more real organics in them. It is great for anending the soil so it drains better, too. Also, organics amends the soil by adding these non-processed ingredients helping microorganisms such as bacteria, fungus, nematoids, micorrhizae to live in the soil and grow and process soil. Worms then like the soil better to do their processing of the soil so that soil is able to pass nutrients to your roses!!! Chemical fertilizers do not help amend the soil and they add salt to the soil which does not help it to be ”living soil.” Authentic organic fertilizers added to the soil help it to drain better passing nutrients to your roses as well. and help roots to grow in soil.
I am careful to not suggest adding individual nutrients as sometimes it is over or under done. Instead, I suggest establishing living soil for your roses and a balanced organic fertilizer regimen.
Also, it is recommended 2 times a year to test your soil in your beds for acidity & nutrients in varous places as soil erodes nutrients in different places and creates imbalanced soil in different parts of your property.. Sometimes adding a little extra nutients of a specific variety is essential to fix a nutrient deficiency.,. When soil is tested , at that time, you will know if a particular nutrient ir more are imbalanced.
Potassium is -good for “all around good rose health, vigor, disease resistance and preventing insects damage.” Insects & disease are less likely to prey on healthy roses.
And balanced nutrition will make the healthiest rose w/ organic living soil and organic fertilizers on a regular regimen.

Thank you for your suggestions-Wonderful! I like the idea of adding sulfate iof potash (potassium) to improve the overall health of the rose to fight off BS & mildew, diseases! Postassium certainly helps with disease resistance! Since potassium is good for “all around rose health and vigor” , , it also, would help with recovering a rose after a flush to bloom eventually.
