The fan leaves were still green, on their undersides & and white/shriveled on top?

2, The temps at ground level & light level, never went over 83 degrees...and I don't spray leaves.

3. I do use a moisture probe to check for the next watering. I've used one since '05.

4. I had them elevated (on a box) too close to the light; I am almost sure of that?...probably about 15 inches away. I did a have a small fan blowing between the plants and the light. One poster (at ICMag) thought it was 'wind burn'. I don't remember anybody reporting that before. They never came closer than 15 inches from the light. I switched to an HPS bulb; thinking it MIGHT be UVb related?..but, the situation never improved and got progressively worse.

5. I drives me nuts, not knowing for sure...:wtf:...cause...I'm starting again..:smokin:...week #3 veg...film at eleven...:jointsmile:
400watts and you bleached it from 15", i dont know about that. i get mine to about 12"-13" from the plants never had a problem unless they get closer then that. and you got to burn alot of leaves to stop growth, sounds more like some kind of a lockout.
