HPS being too close to seedlings is very easy to do.

I have 2x 250 watt HPS' and I sometimes have trouble nuking my plants.
The Grim Reefer Reviewed by The Grim Reefer on . Pics, what's wrong with my plants? Ok as some of you know I've been having trouble with my plants and I took a pic today. Basically it starts out as black specs on the leaves and takes over the whole leaf until its brown and it dies. I've varied the soil, watering schedule, light distance etc...I can't figure it out. A few of the plants are yellow, but no black specs. Rating: 5
