Has anyone experienced this?!??!

Last night I brought two three foot sativas in five gal pots from my backyard to my grow closet, located in my garage. Prior to placing them in the then-dark closet (I am starting them at 12:12 immediately) I sprayed them with some neem oil. This was at 10:00 PM, and my 400W HPS came on at 6:30 AM this morning. I checked the plants around 1:00 PM today, and many of the fan leaves had dull yellowish spots on them. I looked with a 5x glass, and couldn't really see too much in the way of pests. I am guessing that the neem oil spray has something to do with this, but the spray had to have dried in eight hours - right? I'm sorry, I cannot post a pic yet, or I would have. But these spots are freaking me out - I cannot keep these in my backyard any longer, and if I am doing something wrong with this change of location I'd like to know so I can try and correct it. THX. :(

it seems like the neem oil might have done it but it also might have been the temp change for outside...other than that i couldnt tell you...

The only symptom of neem overapplication that I have ever encountered is a darkening of the leaves- they go DARK green and translucent. It's from suffocation.
Yellow spots don't sound particularly like anything to do with the neem.
