Yeah like I said I could be wrong.. But they didnt show up until a couple weeks after I hung them, and they stopped when I removed them. Ever since, I've just used HPS and red spectrum for flowering and haven't had any problems. I suppose there could have been another factor there that I missed, but that was the conclusion I drew from the matter.
edit - also I should explain the circumstances a little better - I was using the shop lights for lower branches that were not getting any light, before I learned about lollipopping, etc. So, they were only getting blue light. They went from producing buds to producing seeds. So, I took them out, and the seeds stopped. Though, they didn't produce much for flowers either. So essentially they went from no light, to blue light, back to no light. Could have just been light depravation, IDK. I do know I haven't had a single seed since I stopped using crappy lights. :D
