This is the answer I was looking for, I already knew its best to go with 2700k but I don't have that what should I expect if flowered with blue spec only??less yield I would assume.The answer to your question is yes you can flower with a 5500k but I don't think that's recommended. I know some 5500k bulbs are considered full spectrum but they still lean more towards a blue light.
So will it work? Yes it will
Should you do it? It's up to you but you would get better results with a light that's more red like a 2700k
