I've seen sunburn and even bleaching as a result of running the lights to close to the canopy.

Personally I like 2 to 6 inches, tho wattage is a factor here with higher wattage units 300+ 10 to 12, I'm willing to accept a little bleaching.  But I'm always watching for any signs of burns.
In my experience a little bleaching doesn't hurt anything, tho to much bleaching tends to slow growth a little and causes a hashish like taste.
Burns of any kind are just bad imo.

Bleaching is white or near white at least.
Yellow is your plant telling you there are problems.

do you run MH for veg?  I know its a hot topic but most growers I know have converted to T5's they say the results are practically identical and with the T5s the plants don't stretch nearly as much because they are like 1.5 inches above the canopies



I have yet seen a set of T5's grow as well as MH.
And if someone is getting stretching under an MH then they are raising their lights to quickly.
MH in fact creates tighter branch spacing.

I've seen them, and grown with them.
They don't have enough peneration to keep me happy.
HID is the only way for me.

I only use cfl's for clones these days.
But that is as far as I'll go with flouro's.
