Spinosad on 2nd week flowering

Hi all growers, usually about 2 weeks before flowering I spray the spinosad on my girls but unfortunately, I'm an idiot, this time I totally forgot this step. I spray it in advance since sometimes the party was ruined in full bloom by thrips but this time the situation is different since yesterday, inspecting leaf by leaf, on one of my girls I found about 6 tiny balls (6 balls in total on 3 leaves of the same branch in the middle of the plant) of a reddish color, but apparently transparent, attached to the main vein of the lower part of the leaf almost as if it came from the same vein and moreover the vein in the part where I found the balls was red / purple. I have never had aphids or red spider mites but I know that they are a great pain in the ass and, even if I still cannot say that I have an infestation, I would like to avoid getting to know these parasites also because I try to keep them under control and I this situation seems absurd. I state that the plants are healthy and apparently do not show any problems except for a few claw leaves caused by a pre-fertilized soil saturated with nitrogen. My questions are the following
1: Being in the second week of flowering, can I safely spray spinosad? (I know it shouldn't be done but the plant is still developing the first flowers and I don't think it's all this big problem but I ask for advice from those who have found themselves in this situation)
2: Could it be that in reality they are not eggs but anything else derived from damage to the leaf? I have no photos unfortunately because my phone is so much shit it couldn't focus and rightfully so these balls are small and my lens had low light batteries so I didn't get a chance to see myself up close.
I thank anyone who has had the patience to read
