My mother has brown all over the leaves??? Don't wat from?? Strain is orange kush got em under 3 t5 lights botanicare nutes in soil... Have pics jus need to figure out how to load em... Thank u guys for all your help!!!!
Thanks again for response.. I'm using Botanicare nutes, Foxfarm(Ocean-Bottom) Soil, 3 24 inch T5 lights-2" away, occasionally I place it in with harvest side under a 600w Hps-18" away from light. I watered n fed with dilluted nutes (900ppm) "Grow" the night before the brown started n didn't notice it that morning.
If you look at the pics, you can see that the brown is in a line. Notice how it's all lined up. That indicates that it's from one of the lights. 2 inches is on the close side. I may be wrong, but I've got a good feeling that your lights are a little too close. I would raise the lights to 4 inches above the plants. That should stop the burning. The plants will still be getting adequate light at 4 inches.
