Rolldaddy- This thread is 5 years old haha, a newer more relevant thread being bumped with this question would have been better. Answer to your question is no, never spray anything on your plants with the lights on. The droplets can magnify and burn your plants, the mist can hit your bulb and cause it to blow. Whatever you decide to use do your research, many products such as the ones you mentioned in the right amount can burn your plants by themselves. I myself prefer floramite to kill these bastards dead when prevention fails.
Peacemonger, we aint got that much time for spraying... lol. 2 X Week? Damn, for a closet maybe... Im talking about for months at a time. Heal, not bandaid.
I thinks its just a good rule of thumb.As for the myth that spraying your plants while lights are on will burn them, I don't buy it.

Thanks for all the input. I started growing in the south and that's when I learned about spider mites. Backthen when I dealth with them And I used avid once and they were all gone.
Now I am in the north east. By reading posts on this site I have learned about broad mites.
I currently do not have a mite infestation. Soon I will be flipping my room to 12/12. When I was at home depot I saw they carried neam oil so I figured I should buy it and use it just a precaution before I flip it. Since this year we had a warm winter I was under the impression
we will have a larger bug population so I figured better safe than sorry.
As for the myth that spraying your plants while lights are on will burn them, I don't buy it. Since I got into this I have allways used hid lights which are the brightest IMO. Also during veg I foliar feed while lights are on, plus I have always misted them with straight water through veg and flower and have never burned my leaves or busted any bulbs. I mist my plants not the light bulb. So what I wad asking is that if neam oil is harsh and if could hurt my girls if I spray them down with that while lights are on? But I guess that doesn't matter. I don't go into my room while the girls are sleeping. During veg or bloom. Even the one time I used avid I did it while lights were on and no side effect. It just got rid of those little bastards
Peace
