Newbie Grow - 1st post - can you see any issues?

Been lurking on the boards awhile trying to read up as much as possible. Never tried to grow before. I have a Secret Jardin dl120, 400 watt hps but dimmed down to 250 watt. My temps are 74 degrees and 54% humidity. They were raised under 4 45watt floresecents and just this week put under the hps. I only started giving them nuts 2 weeks ago, Advanced Nutrients. Since it was my first time I used nirvana autoflowers, I know some people dont like them but Im trying to learn. 5 Jock Horror and 5 bubblelicious. They all sprouted, I have the lights on 16/8 and nuts are given twice a day. I guess this is the part I start to second guess myself. I seen some of the leaves curl upwards so I moved the light up to 20inches from tops, it was at 14 inches. I have a fan blowing lightly accross the tops. Probably better to take the pics when the light is first turned on, but didnt get there in time. Let me know if you see any issues. There are on day 34, not flowering yet.

Thanks for the help.

Whenever taking pictures try taking them just after the lights go out. The yellowish glow makes it hard to see leaf color and/or damage. Really difficult to say anything in he yellowing light. I would say the leaves are extremely yellow.... I know this is because light. You get what im saying thought. A decent camera will have a flash and with a little aiming practise you can get a good shot.

Thanks TokingKing, Ill wait till the lights are off tonight and take another set of pictures.
