I've been battling this problem for almost amonth now. Ive tried everything I can think of, soil, watering, temperature etc...The plants are getting worse by the day and most are dying. I'm thinking somethings wrong with my light. The spectrum is orange so I'm sure it's hps, it's a hydropharm light.

The thing is that I started my first grow with a 150watt hps security light, and everything was fine-in fact the plants were doing amazing. The plants began to yellow as soon as I put the 600watt light on them. What could cause this? I'm thinking about getting a new bulb...
