weird colored leaves

This morning woke up leaves are turning into a light color yellow, my other plant has a black spot on it and also its leaves are turning a lil yellow, any diagnosis on this would really appreciate it.

here is a pic

Yellowing of the leaves could be many things. Could we get a little more info, like what kind of lights, nutes, etc, etc, your using.
I will say just from the picture, looking at the plant in the background, it seems to be a little more light green than it should. Your lights may not be strong enough, or they may be too high above. But that may have nothing to do with your original problem, that was just my first impression from the photo.

well like you said the lights might not be the problem, I'm using a 400 watt hps with 2 54 watts florescent bulbs, I'm using fox farm's grow big, But I think I have it under control, 1 of my fans just stopped working it spiked 86 degrees but now it at 75.
