It's hard to find an answer in a list simply of questions.
If you can't be bothered to type the information, put a picture in your gallery.

The spots are teeny-tiny?- like someone was spray painting in the area and tiny droplets of yellow-white paint drifted on the wind? If so, you might want to look up about spider mites! Look at the bottom side of the leaves. What you are looking for is about half the size of a period on a standard monitor...really small bugs. I hope I'm wrong!

we need the info.,so we can find out wat created it,there can be diff. things that cuz a problem,maybe onething or not...an grannycud be right..mm/
Have you been foliar feeding the plants? Sometimes you can get little yellow spots from foliar feeding when the lights are on....the water droplets can magnify the lights and essentially burn the plants....
If you're NOT foliar feeding...then I suggest spraying the plants with a weak nutrient mixture......this way you can rapidly address any nutrient problems......
And if you do in fact have mites or other buggers....they won't like the moisture either.
It's a catch all suggestion....but of course pictures would be ideal.

Mites aren't a trace mineral deficiency; they are an invertebrate pest that thrives in hot, dry, still air conditions. Lower your temps, increase your ventilation, apply a prophylactic mist of neem oil, and hit them with a chemical pesticide if that's your 'thing'- no=pest strips, pyrethrin foggers, or a systemic. But only if you have at least 3 weeks to harvest!
