Are you sure the burn is from the light? It sounds like nute-burn if the light is 36" away (way too far) from the plants.

I don't know much, but I agree with previous poster... Sounds like your plants are a bit far and maybe nutes... or adjust the pH??? yellow leaves can also mean over watering....
I find rather than judge by the surface being dry, cuz Medicine puts roots so deep, that I will give the pot a bit of a heft. If she's heavy, there's enough water in there, if she's light, she's thirsty. You get used to the feel of the weight and can judge it pretty good i think!
Hope this helps (or if I'm totally wrong PLEEZ somebody tell me so!)
