I have the same insect lumps on my plants. I could never get mine to flower again, and eventually I asked a specialist at a flower show how to do it. She asked me if I was feeding them, and I said I was giving them baby bio. She told me this was what I was doing wrong. I was encouraging them to make a lot of nice green foliage, but no flowers. For the last few years I have given them nothing but water, and they seem almost never to stop flowering! So, if you are feeding your plants : just stop!
