Pictures of the full plant will help. The full space as well, fan locations and such.
Could it not be mechanical damage from the fans blowing too hard and the leaves knocking against each other? My leaves look similar at times when the fan speed is too high
Are those leaves from the bottom of the plant?
I’m doing an OG kush right now, and it has been the most difficult plant I’ve ever grown. Leaves have always had brown spots, and nothing has corrected it. I know this doesn’t help you, but they seem to be very sensitive. Good luck.
If I had to guess it’s either your leaves rubbing together like you were saying or depending on where it’s at on the plant it could be from your watering jug having nute water on it and touching the leaves. I’ve had that too. Pics of whole plant?
Oh joy!!!
Yeah kind of seems like nute burns to me. I’ll tag mentor and get expert opinion. Standby. @Graysin
Help our growmie out Gray🙏🏻
Looks like pests to me. It’s not a professional opinion but I’d absolutely start there before looking at anything else in the grow.
However, knowing the parameters would be good - RH, temps, light, feed schedule, PPMs in/out, pH in/out.
Edit to add: some of the pics are definitely just leaf rub - but others have me more concerned.
G’day mate just an example picture and even after learning about mobile an immobile deficency/excess is still hard too pick but is a good guide to help find out,an the different stages like if is spreading or starting at the top or bottom,is a good read to learn about, gd luck mate looking good still.
