what wrong with my grow?

ok well i ordered some superthrive, stopped watering it as much and gave it a little 7-9-5 fert last night (some leftover nuts i have until my fox farm line comes in the mail). anyway one of my northern skunks is doing great and its leaves are growing nice and broader. these 2 plants below did get somewhat better but still worry me. my other NS hase little yellow dots and its bottom set of leaves have lost all it green....its completely yellow. my blueberry just looks weird lol. so different than the skunks and has a little yellowing as well. whats wrong here? will superthrive help me out.

junkboxer, is that a 400 you are using. It's good to keep the light close to prevent stretching and what not but those plants are still very small. Have you tried raising it to 16 inches or so and see if the plants react well to that. If not move it up a little more. I'm guessing even though air cooled the glass still gets hot, maybe to hot. What are your temps at plant tops w light on?

yes its a 400 watter. i never installed the glass because i have my incoming air built into the reflector so it not only cools the bulb but pours fresh air right onto my plants. my outgoing air in also installed on the reflector taking heat away. with my fan on the temp under the light is warm, not hot. also i juuuuuust raised my light b4 i took those pics so the light was even lower. i thought they were small as well and i wanted them to strech a bit as well so i raised it an inch lol. now that i think about it i should prob raise it a few more.

My guess -they are slightly overfed or have some salt build up. The leaves look a little too dark. Try watering very well with plain phd water. See this website International Cannagraphic Magazine Forums - The Complete guide to Sick Plants,pH, and Pest troubles! for diagnosing sick plants. Great Job, things look pretty good.
