Just curious, do you have a fan blowing directly on the plant?
I’ve seen some similar when I had my fan blowing too hard. I’m just rolling through my second grow, so not an pro. One of the forum gurus will get ya squared up.
Happy growing and good luck!
I would check for pests. Thrip and spider mite damage looks similar.
Let’s see an overall picture of the plant in white light and an idea of how many leaves are affected and where on the plant.
It’s all of them there are four land it’s all the upper leaves I will get some pics tonight before lights come on
Hi all
I have the se issue with the brown spots just like you.
Mine only has happened on one plant I currently have one plant it is a granddaddy purple it was bought from ilgm all my solution I’m using distilled water which I test constantly as a neutral pH in my growing and this is all my first year I grew a batch of white widow I had one and only one plant previous with the same spots and now I have this one and only one plant with the same spots again it’s mostly grown probably got about another 6 weeks it’s an auto anything you can tell me about it I would appreciate it
As far along into flower you are, you can trim and thin all your fan leaves out. It will open up for better air flow and also help with humidity.
