What are the spots?

The leaves were starting to curl down yesterday, so I was like what the heck and took out the 2 40w 2700k and but in 2 23w 6500k and it seemed to bounce back almost immediately lol

Man I wish I could just start a grow journal lol but here's another pic update.

Thanks everybody for the help, as of a couple hours ago i was allowed to start my journal. If you would like to stay updated on how this little one turns out just search my journal named Blue Dream or find it under my profile
