Why do my plants look like this??

Any reasons why the leaves are yellowing? I transplanted these about a week ago and had them under a 600hps, which was too hot, so for the past 4 or 5 days they have been under 3 fluorscents, 80 watts each, 240 total for 9 plants, and they have not really improved. My ph is about 6, and only giving 100ppm of veg nuts as well as magnesium because I thought that was the problem, but apparently not. I am going to try a 600 mh and keep it far away form them to see if it makes a difference. Any suggestions?

heat was more than likely your first problem, maybe poor ventilation, but changing from light to light is not good either. For example, goin from HPS to FLORO to MH isnt beneficial for a plant. It can stress it

what about from reg daylight bulbs 60w to 4 24w cfl 5000k spectrum? lol i finallay got cash after 2 weeks and 2 days into the grow

Do you have a way to test the PH could be nute burn to! Heat could have been it though..I would def check your nute levels though!!

That is iron deficiency, no doubt about it. Get some molasses, add 2 tbs/gal every watering.
