This discolouration is ?
Plants looked healthy 2 days ago, maybe 3 and they still do (can't get pics of full plant yet) but there are a few leaves on each plant suffering the same. Leaves affeted are on top and the middle of the plant, not many but enough for him to be concerned and seek advice. He is growing 2 organically, using pm nutes and 4 using the last of his ionic soil feed. Both methods plants are showing similar symptoms so was thinking it was not nute related ( Open to advide here )
Temps are around 80/82F and humidity is 54.
I did ask how close his lights were, cause they look sort of scorched ??
I have taken a shot from under the leaf too, as its all the way through but not as pronounced.
Thanks in advance.

54 Wan, I am gonna go over later or tomorrow and just make sure for myself. I am swinging towards heat issues. I did see them about a week ago, I had to top them for him and do his clonesand if I recall correctly, he hasn't moved his lights up as they have grown. Am thinking more and more towards heat issues as I am typing. Still hoping for verication though or input as other possible causes.

Cheers

I gotta say it looks a lot like light/heat burn to me - had similar burns on leaves before i got a ventilated reflector.

Heat and light issues. The plant can't deal wid the intensity of Lumens. The cloro is trying to process it but is just gettin fried. Esp being organic with slower plant metabolism. CO2 would help but that's mainly for the rich & famous. Now, is that a controversial theory or what! Or am I jus chatting s#@*!

im going with the heat burn

If this is a guessing game then that is what I would plum for just from the pictures..

It is like the chlorophyll pigment has been cooked in parts of the leaves..
