What am I doing wrong here?

I am doing my first ever indoor grow consisting of 2 autos under 400w HPS HID's. I have given them a couple different nute solutions but have stopped for now due to the yellow spotting on the leaves. I'm attaching a couple current pics from 6/8/16.

You got some bugs in there?

Some gnats waiting for water, do you think that could be it?

You should give more details. What nutes? Did you ph? What medium is that?

I'm using Nitrozime 0-4-4 organic nutes, I haven't checked pH only BC I don't have anything to check it with yet. And the medium is just plain soil and perlite. I water with tap water that's been left out for 24 hours.

welcome to RIU. you should research thrips.
