I totally agree with filling-out the troubleshooting form, but I'd like to hear more about how you water and how often, how you fertilize, and how often, and are you using any additives like hydrogen peroxide, Vitamin B or superthrive?
Also, are you spraying them with something? If you do spray, how often, and is the spray ph'd? Do you raise the lights till evaporated?

Make sure to hit those points when completing the form. :thumbsup:
