if its only the upper leaves, it might be a heat problem, too hot near the top?

looks like nute burn, not heat stress.

what it is ?

"looks like nute burn, not heat stress."

In my experience nutrient burn usually affects the tips as well.

To me it looks like at some stage your lights were too close to the fan leaves. If it doesnt get any worse I wouldnt worry too much about it. Plants are a little like humans though, if you get sun burn on say youre left shoulder, even though the next day the sun may not be hot, it still burns like shit when it hits your left shoulder.

Point being, if it is heat stress and you have adjusted your lamps to the right height, it may continue to stress that particular burnt leaf. Thing to watch for is if more leaves start to brown up.

ok....but I Don't understand...what "nute" is ?

so, in your opinion, the problem is that the plant it's too near to the lamp bulb....not a nutrient problem...
maybe that the problem is that some water drops have fell on that leaves?
(but i don't remember this)

"what "nute" is "

nute burn = nutrient burn.

Are the burn marks getting worse?

Yep Heat, mine did the same to, don't sweat it. just move them away from the heat source.

 

[TheBlaster]

Not to worry about the dead, dried spots on your leafs.
Mine were worse than yours, but are doing great now.
